The interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — figures that govern selectivity coordination downstream. The TM240 trip provides fixed thermal and magnetic settings for overload and short-circuit protection. The insulation voltage is rated at 800 V, and the unit dissipates 10.6 W maximum under full load. The 32 A rating holds from 40 °C through 50 °C ambient. At 55 °C the continuous current derates to 31 A, and at 70 °C it drops to 30 A. The operating temperature range spans -25 °C to +70 °C, with storage limits of -40 °C to +80 °C. The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 3-pole width of 76.2 mm (3 inches) is standard for SENTRON 3VA1 frame sizes, so it drops into existing panel cutouts and busbar arrangements without modification. The depth of 70 mm leaves clearance for rear-access wiring and shunt-trip connections.","metaTitle":"Siemens 3VA1132-5EF32-0KA0 SENTRON MCCB, 3-Pole, 32 A, TM240","metaDescription":"Siemens 3VA1132-5EF32-0KA0 SENTRON molded case circuit breaker, 3-pole, 32 A rated at 40 °C, TM240 thermal-magnetic trip, 187 kA at 240 V.
