Temperature derating is minimal up to 50 °C — still full 32 A — then drops to 31 A at 55–60 °C and 30 A at 65–70 °C. That means in a tightly packed enclosure with ambient near 60 °C you lose 1 A per pole; plan the load schedule accordingly. The 4-pole width (101.6 mm) is the standard 4-module MCCB footprint for this class — it occupies four 25.4 mm positions on a DIN rail or panel-mount plate. The TM220 release has no communication function, no undervoltage release, and no ground-fault monitoring — it's a plain-vanilla thermal-magnetic breaker for line protection. If your design requires a shunt trip, UVR, or ground-fault module, you need the accessory slot version (check the 3VA accessory catalog).","metaTitle":"Siemens 3VA1132-4GE42-0AA0 SENTRON MCCB, 32 A, 4-Pole, TM220","metaDescription":"Siemens 3VA1132-4GE42-0AA0 SENTRON molded case circuit breaker, 32 A rated, 4 poles, TM220 release.
