In a sealed panel or high-ambient enclosure, that 55 °C threshold is the first one to watch — a 4 % derating from nominal means the breaker is still usable for a 30 A continuous load but not a full 32 A feeder. The 15000 mechanical/electrical endurance cycles (latching) suit the breaker for frequent-switching applications like capacitor bank or lighting contactor panels. ## Interrupting capacity across voltage tiers The interrupting capacity drops as system voltage rises: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. For 400 V-class distribution panels common in European and Asian industrial plants, the 75.6 kA figure provides ample headroom for most transformer-fed installations. ## Auxiliary contacts and shunt trip — the integrated trip alarm The integrated auxiliary trip order code 3VA9688-0BL30 is the companion accessory for the shunt trip coil. The trip indicator (mechanical flag) and voltage trigger confirm the breaker state locally.","metaTitle":"Siemens 3VA1132-4EF32-0HH0 SENTRON MCCB, 32 A, 121 kA","metaDescription":"Siemens SENTRON 3VA1132-4EF32-0HH0 molded case circuit breaker, 32 A rated, 121 kA interrupting at 240 V. 3-pole, line protection, TM240 release.
