The Siemens SENTRON 3VA1132-3EF36-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated 32 A at 40 °C, with a TM240 thermal-magnetic overcurrent release and an integrated undervoltage release.
At 240 V the breaker clears 75.6 kA; at 415 V it's rated 52.5 kA, dropping to 32 kA at 440 V and 11.9 kA at 500 V and 690 V.
Rated current holds at 32 A up to 50 °C ambient, then derates to 31 A at 55–60 °C and 30 A at 65–70 °C. In a sealed, uncooled enclosure at 55 °C the breaker still carries 31 A continuous — useful for a crowded panel. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall, fitting standard 3-pole MCCB mounting footprints. Maximum power loss is 13.1 W, which factors into enclosure thermal calculations.
