The magnetic short-circuit trip responds at 325 A, so it clears a bolted fault fast without waiting for a thermal bimetal. Size S2 frame: 55 mm wide, 140 mm tall, 149 mm deep. Mounting position any, so you can lay it sideways in a tight gland-plate layout. Clearance needs: 50 mm above and below, 30 mm to the side, 140 mm forward. That 149 mm depth is the body plus terminals; factor it into your enclosure depth before you cut the backplate. Main current circuit uses screw-type terminals with box terminals — accepts 2x (0.75 to 25 mm²) solid or stranded, or 1x up to 35 mm². For AWG: 2x (18 to 2), 1x (18 to 2). Torque spec: 3 to 4.5 N·m on the main contact screws. Connections arranged top and bottom, which is the standard feed-through layout for a motor branch circuit. ## Environmental and ratings Relative humidity 10 to 95 % during operation. Shock resistance 25 g / 11 ms per IEC 60068-2-27. Installation altitude up to 2 000 m above sea level. Insulation voltage 690 V at pollution degree 3. Surge voltage resistance 6 kV.","metaTitle":"Siemens 3RV5331-4DC10 SIRIUS Circuit Breaker, 25 A, 690 V","metaDescription":"Siemens SIRIUS 3RV5331-4DC10 circuit breaker for starter combinations. 25 A AC-3 at 400 V, 690 V rated, 3-pole, magnetic trip at 325 A.
