Peter,

I cannot tell you whether all UL/CSA Listed/Recognized/Certified circuit
breakers have a minimum 3 mm contact gap, but I always specify that this is
what I need when using breakers as a disconnect device.

Subject:  3mm contact gap for Circuit Breakers

Dear Members,

Can someone confirm that a UL/CSA Listed or 
Recognized/Certified circuit breaker has minimum 3 mm contact 
gap and can be considered suitable as a service disconnect device 
in UL1950/CSA C22.2 950?
