Circuit Breaker Required

[Colin Beagrie]

Good Morning,

Was wondering if anyone can help me out. I am looking for the following type of circuit breaker for a customer of ours. Have looked into modern replacements but can't find any suitable ones so it's looking more likely that we need a direct replacement.

What we are after is the following -

Merlin Gerin
Compact C250NI, 4 Pole Circuit Breaker
250Amp Frame
600V/500VDC
24VDC Under Voltage Coil
2x Auxiliary Contact Block

If anyone has one or more of this type of breaker please contact myself and we can talk business.

Regards
Colin Beagrie

Just Googled it try RS online, not you Tel it was meant for the op but as usual you beat me to it

I have looked at these but there are a couple of issues, it's for an EX offshore panel and due to the certification it has to be a direct replacement or as technically close to the original. The original is a 250Amp frame and that one is a 400Amps frame. The Compact C250NI has no protection device either, it is used as an isolator for a telecoms battery system therefore needs to be 4 pole. Also the rotation handle for the original rotates anti-clockwise for on and newer ones rotate clockwise for on. Have looked at various manufacturers and they all rotate clockwise for on.

Thanks for the replies guys but it really needs to be a direct replacement

I've included some photos of the older circuit breaker

Have you spoken to Schneider? 08706088608 - If they can't help you ...

I have contacted Schneider and I'm just waiting on a response. To be honest my experience with their tech support has been somewhat mixed but I'll wait and see what they come back with. My hope is that I can find someone who has one of these sitting on a shelf somewhere, it would get our customer out of a bit of a sticky one.

Have an online search for obsolete electrics, redundant breakers, rare MCCBs, Salvaged electrical and talk to some of those people, they are they sort who may well have something of the sort on the shelf.
There are a fair few websites that deal with these items.
