The 50 A rating holds flat from 40 °C up to 50 °C; above that it derates gradually to 45 A at 70 °C. It's a straight line-protection breaker for a fixed load. The 100% N-conductor protection means the neutral pole is rated the same as the phase poles, so it's suited for 4-wire systems where the neutral carries full phase current. Front-face IP40 protection keeps dust and tools out of the mechanism in a clean indoor panel.","metaTitle":"Siemens 3VA1150-4GD46-0AA0 SENTRON MCCB, 4-Pole, 50 A, 121 k","metaDescription":"Siemens SENTRON 3VA1150-4GD46-0AA0 molded case circuit breaker, 4-pole, 50 A rated, 121 kA at 240 V.
