Its headline rating is the 70 kA breaking capacity at 415 V (class H), which means it can safely interrupt fault currents up to that level without upstream cascading — critical for high-fault panels where a lower-rated breaker would need a current-limiting upstream device. Mounts in a standard DIN-rail or panel-mount enclosure. The nut keeper kit is included, which simplifies panel assembly by retaining the mounting nuts during installation. The two auxiliary switches (HQ) and one trip alarm switch (HQ) provide remote status feedback for PLC or SCADA inputs.","metaTitle":"Siemens 3VA1112-6MH32-0AH0 Circuit Breaker, 125A, 70kA @ 415","metaDescription":"Siemens 3VA1112-6MH32-0AH0 IEC frame 160 MCCB, 125A, 70kA breaking capacity at 415V.
