Ground fault detection is not included, so if that's required, you'd need an external relay or a different variant. ## Breaking capacity and voltage ratings At 240 V AC this breaker interrupts 100 kA; at 400 V AC it's rated 65 kA. At 690 V AC the breaking capacity drops to 2 kA, so for 690 V primary circuits verify the available fault current stays under that. The rated insulation voltage spans 20 to 690 V, covering standard low-voltage distribution. The 55 mm width and 149 mm depth fit standard panel layouts; clearance requirements are 50 mm above and below, 10 mm to the side, and zero forward/backward clearance needed. Main circuit terminals are screw-type, accepting 2× (1 to 35 mm²) or 1× (1 to 50 mm²) solid or stranded copper. Torque to M6 for the main contacts.","metaTitle":"Siemens 3RV2431-4WA10 SIRIUS Circuit Breaker, Class 10, 65 k","metaDescription":"Siemens 3RV2431-4WA10 SIRIUS circuit breaker for transformer protection.
