Rated In=125 A with a thermal-magnetic TM220 trip unit, the overload protection is adjustable Ir=88…125 A and the instantaneous magnetic pickup is fixed at Ii=10 × In (1250 A). Rated for 3-pole line protection in distribution boards, motor control centers, and industrial switchgear. The clamp connection terminals accept copper or aluminum conductors — no lug kit needed for most panel builds. The frame 160 footprint is standard across the 3VA1 family, so busbar connections and mounting hardware are consistent if you are coordinating upstream and downstream breakers.","metaTitle":"Siemens 3VA1112-5EE36-0AC0 Circuit Breaker, 55kA @ 415V, 125","metaDescription":"Siemens 3VA1112-5EE36-0AC0 IEC frame 160 MCCB, 55kA breaking capacity @ 415V, 3-pole, TM220 thermal-magnetic trip, In=125A, Ir=88-125A, Ii=10xIn.
