That's a shallow curve, so you don't lose much if the panel runs warm. The 75.6 kA at 240 V is the headline interrupting number, but check the other voltages if your system is 415 V (52.5 kA), 440 V (32 kA), or 690 V (11.9 kA). The TM220 trip means magnetic pickup is fixed at 220 A — no field-adjustable short-time delay, so it's a straight feeder or branch breaker, not a main with selective coordination requirements. Dimensions are 130 mm high, 76.2 mm wide (3 inches), 70 mm deep. That's a compact 3-pole footprint — fits a standard MCCB slot in a SENTRON distribution board or a generic panel. IP40 on the front, so it's fine inside an enclosed panel; no special gasketing needed.","metaTitle":"Siemens 3VA1150-3EE36-0AA0 SENTRON MCCB, 50A, 75.6kA","metaDescription":"Siemens SENTRON 3VA1150-3EE36-0AA0 molded case circuit breaker. 3-pole, 50A at 40°C, TM220 trip. 75.6kA at 240V.
