The TM240 thermal-magnetic release handles overload and short-circuit response without communication or voltage-trip options — a straightforward, non-electronic trip unit that doesn't introduce noise into the control wiring. Rated breaking capacity hits 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — figures that give an electrical engineer real SCCR headroom for coordinating downstream devices in a distribution panel. The 4-pole MCCB measures 70 mm deep by 101.6 mm wide by 130 mm tall — a footprint that fits standard SENTRON panel cutouts and busbar systems.","metaTitle":"Siemens 3VA1150-6EF42-0AA0 SENTRON MCCB, 50 A, 4-Pole, 220 k","metaDescription":"Siemens 3VA1150-6EF42-0AA0 SENTRON molded case circuit breaker, 50 A at 40 °C, 4-pole, TM240 release, 220 kA at 240 V.
