Hello, I bought these pushbuttons.

And I need to buy contactor blocks for this. I am not sure how to buy the correct one. Can anyone help me with this. Is this the correct one :

This one one says Harmony pushbuttons and switches. XB4 series is different from this. Thats what I thought. So the contactor blocks for XB4 series wont work with this. That was my assumption. Am I wrong.

 

The XB2B range of PB was originally designed and sold by Telemecanique, since then Group Schnieder have taken them over.
You require to order the PB/SW, switch body and N.C. or N.O. switch unit.
It appears they have changed the name or come up with an alternative product (Harmony?).
I have used the XB2B versions extensively in the past,
Also I see these are sold on ebay from China, considerably cheaper, probably knock off's ?
The XB2B and ZB4B do not appear to be compatible/interchangeable ?

 

ZB4BW363 is just the head (colour blue). There are no contacts.
ZB4BW0B61 contains the blue LED and contacts.

Watch the video on how to remove the contact block.

The actuator, body, and switch unit are normally all ordered separately ZB4B and ZB2B range do not appear to be interchangeable.

 

The XB4 requires only 1 screw to tighten on the mounting collar verses 2 on the XB2. This allows easier installation. The XB4 push buttons can accept 3 contact blocks side-by-side-by-side for a total of nine contacts on non-illuminated devices. Using the XB4 Protected LED light modules and contacts on each side will allow shallower depth than the XB2 on illuminated devices.

 

also, note to topic starter, you can scroll down on those Farnell pages and see related parts. part number for the contact is right there. documentation or catalog will show you the rest. also Schneider makes it possible to order assembled buttons/indicators (single article number for combos like pilot + lamp+ contacts). they have them in button boxes too

 

Sorry but I am confused, so I am supposed to buy the Xb4 now, that is correct one. which means

ZB4BW0B61 for Harmony XB4 series actuators.
