That interrupting rating means it clears a fault up to 36 kA without welding or rupturing — enough for most industrial distribution panels downstream of a transformer. The TM220 thermal-magnetic trip unit gives fixed thermal (Ir=18…25 A) and fixed magnetic (Ii=12.8 x In) protection, so the breaker coordinates with typical motor-start and feeder loads without needing a separate adjustment module. The shunt trip allows remote tripping from an E-stop or PLC output; the aux switches give status feedback to a DCS or panel lamp. At 25 A and 36 kA SCCR, it fits in a standard 3-pole MCCB footprint — watch the space for the shunt trip and auxiliary switch stack, which adds depth behind the cover. The nut keeper kit prevents loose hardware during transport, a common failure point on field-installed breakers.","metaTitle":"Siemens 3VA1125-4EE32-0KH0 Circuit Breaker, 36kA @ 415V, 25A","metaDescription":"Siemens 3VA1125-4EE32-0KH0 IEC frame 160 circuit breaker, breaking capacity class S, Icu=36kA @ 415V, 3-pole, TM220, In=25A, shunt trip, 2 aux switches.
