It carries a rated current of 50 A at 40 °C, with a breaking capacity of 75.6 kA at 240 V — enough to safely clear high-fault currents in industrial distribution panels without cascading upstream.
The 50 A rating holds steady from 40 °C up to 50 °C, then derates to 49 A at 55 °C and 45 A at 70 °C — a thermal curve that matters if this breaker sits in a warm enclosure or near other heat sources. Breaking capacity drops with voltage: 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V or 690 V.
The 3VA1150-3EF32-0JH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard SENTRON MCCB footprint that bolts into a distribution panel or switchboard.
