This SCCR profile suits it for high-fault panels where upstream coordination demands a robust interrupting rating across the voltage range. ## Thermal-magnetic trip and auxiliary switch fit The overcurrent release is a TM240 thermal-magnetic type — fixed thermal and magnetic elements, no electronic adjustment. That means the trip curve is set at the factory; if your load profile requires a different curve, this is not the variant to spec. ## Thermal derating and panel space Current rating holds at 32 A from 40 °C up to 50 °C, then derates to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — standard SENTRON 3VA footprint for a 3-pole frame. Width of 76.2 mm (3 in) matches the typical 3-pole MCCB slot in a panel layout.","metaTitle":"Siemens 3VA1132-4EF32-0AG0 SENTRON MCCB, 32 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1132-4EF32-0AG0 molded case circuit breaker, 32 A rated, 3-pole, breaking capacity 121 kA at 240 V.
