Rated 32 A at 480 V and 32 A at 600 V, with a breaking capacity of 50 kA at 400 V and 100 kA at 240 V. Mounting position any orientation — no derating for side or upside-down mounting. Clearance: 50 mm upward and downward, 10 mm to the side, zero forward or backward. Dimensions: 55 mm wide, 140 mm high, 149 mm deep. ## Electrical ratings and environment Rated voltage range 20 to 690 V AC. Breaking capacity varies by voltage: 100 kA at 240 V, 50 kA at 400 V, 8 kA at 500 V, 4 kA at 690 V. That drop-off at 690 V is typical for a 32 A frame — the arc extinction limits the high-voltage interruption. Operating temperature -20 to +60 °C, storage -50 to +80 °C. No ground-fault or phase-failure detection built in — this is a thermal-magnetic or electronic motor-protective breaker, not a full power monitor. Main contact terminals are M6 bolts.","metaTitle":"Siemens SIRIUS 3RV2332-4EC10 Circuit Breaker, 32 A, 50 kA at","metaDescription":"Siemens SIRIUS 3RV2332-4EC10 circuit breaker for starter combinations. 32 A rated at 480/600 V, 50 kA breaking capacity at 400 V.
