The 690 V AC rated operating voltage covers most industrial line-to-line systems, including 600 V class in North America. Measures 76.2 mm wide, 129.4 mm tall, and 75.1 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. ## What it does not include This is a bare thermal-magnetic MCCB — if your application requires remote tripping or ground-fault signaling, you need the accessory version or an external relay. The TM210 release is designed for system protection (cable and busbar), not motor overload protection; for motor circuits, pair it with a separate overload relay.","metaTitle":"Siemens 3VA4150-4ED34-0AA0 SENTRON MCCB, 50A, 65kA at 240V","metaDescription":"Siemens 3VA4150-4ED34-0AA0 SENTRON molded-case circuit breaker, 3-pole, 50A at 40°C, 65kA interrupting at 240V AC.
