Its TM240 thermal-magnetic release handles the overload and short-circuit curve; the shunt trip (STL) lets a remote signal or emergency-stop chain drop the breaker independently of the bimetal. Breaking capacity is the headline: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. The 690 V rating is lower but still covers most motor-circuit fault levels at that voltage. Dimensions are 76.2 mm wide, 130 mm tall, 70 mm deep — a standard 3-pole MCCB footprint that fits SENTRON distribution blocks and most DIN-rail or screw-mount panel layouts. The 70 mm depth leaves clearance for rear-connected busbars or cable ducts behind the breaker. Latching endurance is rated at 15 000 operations, which covers years of manual switching in a panel that sees weekly isolation. That covers unheated warehouses and outdoor enclosures in temperate climates. The integrated auxiliary trip is a separate order code (3VA9688-0BL33) — verify it matches your panel's shunt-trip voltage before wiring.","metaTitle":"Siemens SENTRON 3VA1132-4EF36-0KH0 MCCB, 32 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1132-4EF36-0KH0 molded case circuit breaker, 32 A rated, 121 kA breaking at 240 V.
