The Siemens 3VM1140-4GE42-0AA0 is a 4-pole circuit breaker from the 3VM1 IEC frame 160 family, rated 40 A continuous with a breaking capacity of 36 kA at 415 V AC (class S). The TM220 thermal-magnetic trip unit gives an overload protection range of 28 A to 40 A (Ir adjustable) and a fixed short-circuit pickup at 10 x In (400 A). The 100% N conductor protection means the neutral pole is fully rated, not reduced — important for 4-wire systems where neutral loading is non-trivial.
RoHS compliant since 01 June 2012.
