The ABB XT2HE4100BFF000XXX is a 4-pole molded case circuit breaker from the XT2H 160 TMA series, designed for three-phase systems where the neutral pole requires coordinated overcurrent protection alongside the phase poles. The 4-pole configuration switches and protects all four conductors — three phases plus neutral — in a single unit.
It is a 4-pole molded case circuit breaker, suitable for three-phase-plus-neutral protection in TN-S and TN-C-S systems.
No. The XT5NU340ABNF000XXX is a 3-pole 400 A unit on a larger XT5NU frame. The XT2HE4100BFF000XXX is a 4-pole breaker on the smaller XT2H frame, so bus bars and mounting footprint would need rework.
