Its interrupting capacity hits 121 kA at 240 V AC and still holds 75.6 kA at 415 V AC — enough headroom for high-fault utility feeds or transformer secondaries without cascading upstream breakers. The auxiliary contact package includes 2 auxiliary switches plus 1 separate trip-alarm switch (HQ type), which gives a dedicated signal for the breaker's open-on-fault state — useful for PLC alarm logic or remote annunciation without sharing the aux contact that also signals manual switching. The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that fits Siemens' own panel-mounting accessories and most DIN-rail adapter plates. The undervoltage release (UVR) is factory-integrated, so no separate coil module to wire in the panel; the release design is the 3VA9608-0BB24 auxiliary trip block. Current derating starts above 55 °C: at 65 °C the breaker carries 29.44 A, at 70 °C it's 28.8 A.","metaTitle":"Siemens 3VA1032-4ED36-0CH0 SENTRON MCCB, 32 A, 3-Pole, 121 k","metaDescription":"Siemens 3VA1032-4ED36-0CH0 SENTRON molded case circuit breaker, 32 A rated current, 3-pole, 121 kA breaking capacity at 240 V.
