It switches motor loads up to 5.5 kW at 400 V AC-3 duty, with a breaking capacity of 50 kA at 400 V AC. Width is 45 mm, depth 81 mm, height 90 mm. Main and auxiliary/control circuits use spring-loaded terminals, accepting 2x (0.25 to 2.5 mm²) solid or 2x (0.25 to 1.5 mm²) finely stranded with ferrule. AWG range 24 to 14 for the main contacts. Strip length 8 mm avoids whiskers under the cage. Mounting position any; no derating for orientation. ## Electrical Ratings and Protection Rated insulation voltage 690 V. Breaking capacity at 240 V AC is 100 kA; at 400 V AC, 50 kA; at 500 V AC, 3 kA; at 690 V AC, 2 kA. Power dissipation in hot operating state is 9.25 W total, 3.1 W per pole. Surge voltage resistance rated at 6000 V. Maximum operating frequency at AC-3 is 15 operations per hour.","metaTitle":"Siemens 3RV1011-1KA20-ZW96 SIRIUS Motor Circuit Breaker, 12","metaDescription":"Siemens SIRIUS 3RV1011-1KA20-ZW96 motor-protective circuit breaker. 12 A continuous, 5.5 kW at 400 V, CLASS 10 trip.
