For a panel that runs warm — say 55 °C inside the enclosure — the breaker is good for 49 A continuous, not the full 50 A. If your motor FLA is 48 A and the panel ambient hits 65 °C, this breaker is marginal; step up to the next frame or improve ventilation. The 76.2 mm width (3 in) is the standard 3-pole MCCB footprint for this frame size — it occupies three 25.4 mm module positions on a DIN rail or mounts directly to a backplate via the screw terminals. The 70 mm depth leaves clearance for wiring gutters in a typical 200 mm deep enclosure.","metaTitle":"Siemens 3VA1150-6MH36-0AA0 SENTRON MCCB, 50 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1150-6MH36-0AA0 molded case circuit breaker, 50 A rated, 3-pole, TM120M release.
