It carries a 50 A continuous rating at 40 °C with a TM210 thermal-magnetic release, and delivers 75.6 kA interrupting capacity at 240 V AC — enough for high-fault utility feeds or transformer secondaries. This is the single-pole version, so it fits branch circuits where you need phase isolation without a multi-pole block. On the DC side it's rated for 125 V, making it usable in control power supplies or battery-backed circuits. Above that, it starts to pull back: 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. If you're stuffing this breaker into a hot panel — say next to a drive or a transformer — that derating curve is what governs real-world ampacity, not the nominal 50 A. The 75.6 kA at 240 V is the headline number, but the real coordination value is the 9 kA at 415 V. For higher fault levels you'd step up to a higher-rated SENTRON frame or add a current-limiting upstream device. At 25.4 mm wide (one inch exactly), 130 mm tall, and 70 mm deep, this breaker occupies a single-pole slot in a standard SENTRON 3VA mounting base.","metaTitle":"Siemens 3VA1150-4ED16-0AA0 SENTRON MCCB, 1-Pole, 50 A, 75.6","metaDescription":"Siemens SENTRON 3VA1150-4ED16-0AA0 molded case circuit breaker, 1-pole, 50 A rated at 40 °C, 75.6 kA breaking at 240 V.
