Its 75.6 kA interrupting capacity at 240 V gives headroom for high-fault panel applications, and the 800 V rated insulation voltage (Ui) suits it for 480 V and 600 V distribution systems. This MCCB delivers 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The 600 V DC max rated operational voltage (Ue with DC) also opens the door for DC bus protection in VFD lineups. Rated 50 A from 40 °C through 50 °C, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. Dimensions are 70 mm depth, 101.6 mm width, 130 mm height — a standard 4-pole MCCB footprint that mounts on a DIN rail or panel-mount base. The 100% N-conductor protection design means the neutral pole is fully rated, not reduced, so it handles the same continuous current as the phase poles.","metaTitle":"Siemens 3VA1150-3GE42-0AA0 SENTRON MCCB, 50 A, 4-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1150-3GE42-0AA0 molded case circuit breaker, 50 A rated at 40 °C, 4-pole, TM220 release, 75.6 kA breaking at 240 V.
