The interrupting capacity hits 75.6 kA at 240 V and 52.5 kA at 415 V, which covers most low-voltage fault scenarios in industrial and commercial mains. ## Breaking capacity across voltages — the so-what The 75.6 kA at 240 V is the headline figure, but the real-world selector is the 52.5 kA at 415 V — that's the common 400 V-class industrial supply. At 440 V it still holds 32 kA, and at 500 V or 690 V it drops to 7.5 kA. The 3VA1050-3ED36-0JH0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without surprises.","metaTitle":"Siemens 3VA1050-3ED36-0JH0 SENTRON MCCB, 50A, 3-Pole, 70mm D","metaDescription":"Siemens SENTRON 3VA1050-3ED36-0JH0 molded case circuit breaker, 50A rated at 40-50°C, 3-pole, 75.6kA at 240V.
