EasyPact EZC circuit breaker EZC400N - TMD - 350 A - 3 poles 3d - EZC400N3350N
This is a 350A circuit breaker for EasyPact EZC400N.
This product can work below rated operational voltage(Ue) 440VAC at 50/60Hz.
The ultimate breaking capacity(Icu) is 50kA at 440V, in terms of complete range Ics=100%Icu(Ics= 50%Icu at 440V.
This version of product is designed 3 poles frame with detection on 3 poles,equiped TMD trip unit for thermal-magnetic protection.
It is compliance with standard IEC60947, CE certification and some independent lab(KEMA,ASEFA,TUV) or third-party Tilva.
This device is certified for operation in pollution degree III environment as defined by IEC60947, and pass the test of extremely atmospheric conditions.
Device can be mounted vertically or horizontally in a metal enclosure,and against from safety risk by padlocking.
The degree of protection is IP40 for direct rotary handle,and IP54 for extended rotary handle.
This series have slots used for indication or voltage release auxiliaries positioning , depending on where it is inserted in the device behind the front cover of circuit breaker.
The fixed dimension is 140mm(width),255mm(height),110mm(Depth).
