Any mounting position is allowed, so vertical or horizontal busbar runs work. Terminal capacity: accepts up to 2× 25 mm² or 1× 35 mm² solid or stranded at the main contacts, with M6 screw-type terminals for the main current circuit. ## Breaking capacity and clearances Breaking capacity: 100 kA at 240 V, 30 kA at 400 V, 5 kA at 500 V, 2 kA at 690 V. Required lateral clearance: 10 mm at the side, 50 mm upwards, 50 mm downwards, 0 mm forwards and backwards. At 240 V no clearance is required. Depth is 149 mm, height 140 mm, width 55 mm.","metaTitle":"Siemens 3RV2031-4EA10-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV2031-4EA10-ZX95 SIRIUS motor protection circuit breaker.
