Dimensions are 130 mm high, 101.6 mm wide, 70 mm deep — that 70 mm depth is the key fit number when you're swapping into an existing panel can depth. Ambient temperature derating starts at 55 °C: full 50 A up to 50 °C, then 49 A at 55 °C, 48 A at 60 °C, down to 45 A at 70 °C. ## What the TM220 release means for coordination The TM220 designation tells you the thermal element is fixed at 50 A (the 220 indicates the frame size and release family), and the magnetic pickup is also fixed — no interchangeable trip units or dial-adjustable settings. That simplifies ordering but means you need to verify the short-circuit pickup level matches your downstream device coordination. For selectivity studies, the interrupting curve at each voltage level (75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, 11.9 kA at 500 V and 690 V) is what you plug into the coordination study.","metaTitle":"Siemens 3VA1150-3GE46-0AA0 SENTRON MCCB, 50 A, 4-Pole","metaDescription":"Siemens 3VA1150-3GE46-0AA0 SENTRON molded case circuit breaker, 50 A, 4-pole, TM220 release, 75.6 kA at 240 V.
