That 50 A holds steady up to 50 °C; at 55 °C it derates to 49 A, and at 70 °C it's 45 A (–). This MCCB carries a 76 kA interrupting rating at 415 V, 53 kA at 440 V, and 12 kA at 500 V (–). That's the short-circuit current it can interrupt at each voltage level — critical for selectivity coordination downstream of a transformer. Front-face protection is IP40 — sealed against tools and solid objects larger than 1 mm, but not dust-tight. In a cement plant control room that sees clinker dust infiltration, you'll want it inside a gasketed enclosure, not exposed open-air. The 70 mm depth and 101.6 mm width fit standard panel-mount cutouts for 4-pole MCCBs in this class. Minimum operating current is 1 A. Maximum power loss is 15 W. The N-conductor protection is rated at 100%.","metaTitle":"Siemens 3VM1150-4GD42-0AA0 SENTRON MCCB, 50A, 4-Pole, 121kA","metaDescription":"Siemens 3VM1150-4GD42-0AA0 SENTRON molded case circuit breaker, 50A rated at 40°C, 4-pole, TM210 release.
