Eaton and Moeller Switchgear and Controls, New Zealand

RFQ / Eaton, Moeller and Klöckner-Moeller

If your switchgear says Moeller, it is Eaton. The part numbers came through the acquisition largely unchanged, so a DILM contactor or a PKZM motor protective switch is the same product whichever name is on the front. Send the part number and the badge does not matter.

Moeller switchgear is on a great deal of New Zealand plant, particularly on European machinery and in panels built through the nineties and two thousands. Much of it is still current product under a different name.

Reference pages

Page	Covers
Contactors and motor protection	DILM frames and coil voltages, ZB overloads matched to the contactor, reading a PKZM setting range, auxiliary contact blocks as separate parts, and what is actually replaceable

The badge history

Badge	Era
Klöckner-Moeller	The oldest labels you will find on a panel
Moeller	The name most people still use
Eaton	Current owner. Often shown as Eaton Moeller series
Cutler-Hammer	Eaton's North American switchgear name
Bussmann	Eaton's fuse business

A DILM9 badged Moeller and one badged Eaton are the same contactor. That is unusually good news, because it means a lot of what looks obsolete on an old panel is still in production.

So do not assume a Moeller part is unobtainable. Send us the number and we will tell you whether it is current, superseded or genuinely obsolete. On this brand the answer is more often current than people expect.

Same situation as Indramat on our Bosch Rexroth page and Emerson on the Control Techniques page.

M22 pilot devices are three parts, not one

The most immediately useful thing on this page, because it turns a large order into a small one.

An M22 pushbutton is assembled from separate components that all have their own part numbers.

Part	What it is
Front element	The button, selector, mushroom head or indicator lens
Fixing adapter	The mounting collar behind the panel
Contact blocks	Normally open and normally closed, stacked as needed
LED element	On illuminated versions, and voltage specific

So a cracked button head is a front element, not a whole assembly. A contact that has stopped making is a contact block. A lamp that has failed is an LED element.

Symptom	Order
Button broken or worn	Front element
Button works, circuit does not make	Contact block
Lamp out, button fine	LED element, in the right voltage
Legend plate faded	Legend plate
Whole station damaged	The assembly and the enclosure

Tell us the symptom and we will quote the part rather than the assembly. On a panel with twenty pushbuttons that difference is significant.

Emergency stops are the exception worth flagging. An E-stop is a safety device, its contact blocks are usually positively opening, and substituting an ordinary contact block into one is not acceptable. Tell us if the device is an E-stop and we will quote the correct parts.

Motor protection: the setting is in the part number

Covered in detail on the contactors page, and worth flagging here.

A PKZM motor protective circuit breaker carries its current setting range in the part number, so a number that ends in a figure like 6.3 covers a range up to that current.

That has to bracket the motor's full load current. Too high and the motor is not protected. Too low and it trips on start.

So send us the motor nameplate full load current as well as the part number, and we will confirm the range is right rather than just matching the number.

The easy relay holds the machine logic

The same pattern that runs through this whole site, on a device people treat as a component rather than a controller.

An easy relay is a small programmable controller. It runs a program, and on plenty of machines that program is the entire control scheme.

Situation	Outcome
Program backed up, or on a memory card	Fit a replacement, load it, run
Program only inside the relay	Somebody works out what the machine did, from the wiring
Several identical machines	One backup covers all of them

These get overlooked precisely because they look like a relay. A small grey box on a DIN rail does not read as a PLC, so nobody thinks to back it up, and the logic is often undocumented because it was written by whoever built the panel.

If you have easy relays, get the programs off them. A memory card is inexpensive and it turns the device into a swap.

The same applies to XC PLCs and XV panels, and the general principle is on the RFQ page.

Breakers: the trip unit may be the part

Symptom	Consider
Nuisance tripping	Trip unit settings, and the actual load
Wrong rating for a changed load	A different trip unit rather than a new breaker
Auxiliary or alarm contact needed	An accessory that clips in
Shunt trip or undervoltage release needed	An accessory
Handle or door interlock damaged	Operating mechanism parts
Breaker damaged by a fault	The breaker

Moulded case breakers take a substantial range of accessories, and a good proportion of enquiries that arrive as a breaker turn out to be an accessory, a trip unit or an operating mechanism.

Tell us what you actually need it to do and we will quote the smaller part where there is one.

Note that after a breaker has cleared a serious fault it may not be fit to return to service. That judgement belongs with whoever is responsible for the installation.

Before ordering a replacement

Symptom	Check first
Contactor buzzing or chattering	Coil voltage and the control supply, not the contactor
Overload tripping repeatedly	The setting against the motor nameplate, and the load
Motor protective switch trips on start	Setting range and starting duty
Pushbutton circuit not making	The contact block, not the whole device
Indicator lamp out	The LED element and its voltage
Machine behaving oddly with no fault shown	Is there an easy relay running the logic
Breaker nuisance tripping	Trip unit settings and the real load
Part looks obsolete	It may still be current under the Eaton name

What to send us

The full part number, whatever badge it carries.

The coil voltage, on a contactor or relay.

The motor nameplate current, on anything protecting a motor.

A photo of the device in the panel, which shows auxiliary blocks, overloads and how it is mounted.

What failed, because a contact block, an LED or a coil may be the answer.

Whether the device is safety related, particularly on E-stops and safety relays.

What we can supply

Motor control. DILM contactors and DILA relays, ZB and ZEB overloads, PKZM and PKE motor protective switches, auxiliary contact blocks and accessories.

Protection. FAZ and PL miniature breakers, RCDs and RCBOs, NZM moulded case breakers with trip units and accessories, isolators and Bussmann fuses.

Pilot devices. M22 front elements, contact blocks, LED elements, fixing adapters, legend plates and enclosures.

Control. easy relays and memory cards, XC PLCs, XV panels and XN300 I/O.

Drives. PowerXL DA1, DC1 and DE1, plus the legacy M-Max and DF51 ranges.

Safety. ESR5 relays and LS position switches, supplied to your specification.

Legacy Moeller. Where a part is genuinely obsolete we source surplus, and where it is still current under Eaton we say so and quote it new.

We buy Eaton and Moeller

Legacy Moeller switchgear resells steadily, particularly contactors, motor protective switches and panel-front devices from stripped machines.

Keep overloads with the contactors they were mounted on, auxiliary blocks in place, and easy relays with any memory card. See Sell To Us.

Common questions

Can you get a part that is not listed on your site?
Usually. The site shows what we hold, not what we can source.

My panel says Moeller. Is that Eaton?
Yes. Same product line, and a lot of it is still in production.

Do I need a whole pushbutton?
Usually not. The front element, the contact blocks and the LED are separate parts.

My contactor buzzes.
Look at the coil voltage and the control supply before replacing it.

How do I size a motor protective switch?
The setting range has to bracket the motor's full load current. Send the nameplate.

What is an easy relay?
A small programmable controller. If you have one, get the program backed up.

Do you supply used equipment?
Where a part is genuinely obsolete, yes. Where it is still current we would rather quote new.

What is the lead time?
Ex stock items ship the next working day within New Zealand. We give you a firm lead time with the quote.

Do you quote in NZD?
Yes, in NZD including GST for New Zealand customers.

Send us your part numbers

Whatever badge is on them. And tell us what failed, because on this brand the contact block, the coil or the LED is very often the whole answer. Quotes in NZD including GST.
