That's a solid thermal curve for a warm panel or a crowded enclosure. Breaking capacity is where this unit earns its keep: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 690 V. That means remote tripping and status feedback are wired in from the factory — no extra add-on modules to buy and fit. It's a straight line-protection breaker, sized for the main feed. Footprint is 70 mm deep by 76.2 mm wide by 130 mm tall — standard 3-pole MCCB envelope for a 50 A frame.","metaTitle":"Siemens 3VA1150-6EF36-0HH0 SENTRON MCCB, 50 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1150-6EF36-0HH0 molded case circuit breaker, 50 A, 3-pole, 220 kA breaking capacity at 240 V.
