The interrupting ratings tell you where this breaker can live without blowing upstream: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. That UVR means the breaker drops out if control voltage falls below a threshold, which is handy for safety circuits or emergency-stop chains where you want the breaker to open on loss of control power. IP40 on the front means it keeps out tools and small wires but isn't sealed against water — fine inside a clean panel, not for washdown zones. The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — that 70 mm depth is shallow enough to fit most standard panel depths without hitting the backplate. No communication function, no phase failure detection, no ground fault monitoring — this is a straight thermal-magnetic breaker with an undervoltage release and auxiliary contacts. That -25 °C low end means it's fine for unheated enclosures in most climates, but if your panel sits outside in a Minnesota winter, the storage minimum covers shipping and idle time.","metaTitle":"Siemens SENTRON 3VA1112-5EF32-0DH0 MCCB, 125 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA1112-5EF32-0DH0 molded case circuit breaker, 125 A, 3-pole, line protection, TM240 release, 187 kA at 240 V, IP40 front.
