No ground fault detection on this variant. ## Breaking capacity across voltage levels The interrupting capacity varies by line voltage: 100 kA at 240 V, 30 kA at 400 V, 4 kA at 500 V, and 2 kA at 690 V. For 480 V systems it's rated 52 A continuous, and at 600 V also 52 A continuous. Maximum switching frequency under AC-3 duty (motor starting) is 15 operations per hour — fine for conveyor or pump cycling, but not for rapid reversing applications. ## Dimensions and clearances Physical footprint: 75 mm wide, 140 mm tall, 149 mm deep. Required clearances for heat dissipation: 50 mm above and below, 10 mm to the side, zero forward or backward clearance needed.","metaTitle":"Siemens 3RV2131-4WA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2131-4WA10 SIRIUS motor protection circuit breaker with overload relay function, Class 10 trip, 30 kA breaking capacity at 400 V.
