The interrupting capacity is the headline spec here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. The TM240 overcurrent release provides thermal-magnetic protection; the shunt trip (STL) design allows remote tripping via a separate control signal, with the integrated auxiliary trip specified as 3VA9688-0BL30. Dimensions are 70 mm deep by 76.2 mm wide by 130 mm tall — a standard 3-pole MCCB footprint that fits most SENTRON distribution panels and retrofit slots. IP40 on the front means protection against tools and small wires entering the enclosure face; the rear and sides are not sealed, so the breaker should be installed inside a panel with a higher overall IP rating if washdown or dust ingress is a concern. ## Selectivity and coordination considerations For an MRO planner or site electrical engineer evaluating this breaker for a line-down spare: the 50 A rating and high interrupting capacity (187 kA at 240 V) make it suitable for main or feeder duty where downstream breakers need to be selectively coordinated. The TM240 release provides a fixed thermal curve and magnetic trip — not adjustable, so coordination studies should verify that the instantaneous trip setting does not overlap with downstream device curves.","metaTitle":"Siemens 3VA1150-5EF36-0HA0 SENTRON MCCB, 50 A, 187 kA at 240","metaDescription":"Siemens 3VA1150-5EF36-0HA0 SENTRON molded case circuit breaker, 3-pole, 50 A rated, 187 kA at 240 V interrupting capacity.
