The main circuit uses spring-loaded terminals — no screw tightening needed, which speeds panel wiring and eliminates the risk of loose connections on high-vibration motor circuits. Clearance requirements: 50 mm upwards and downwards, 30 mm at the sides — zero clearance forwards and backwards. That means the breaker can sit flush against the back panel and the enclosure door, but needs breathing space above and below for arc quenching and thermal dissipation. ## Switching capacity and coordination At 230 V, the motor power rating is 0.2 kW. The auxiliary contact ratings cover a range of control voltages: 1 A at 24 V, 0.5 A at 120/125/230 V, and 0.15 A at 60 V. The maximum operating rate is 15 switching cycles per hour for AC-3 and AC-3e duty — adequate for motor start/stop applications but not for high-speed jogging or reversing.","metaTitle":"Siemens SIRIUS 3RV2011-0KA25 Motor Protection Circuit Breake","metaDescription":"Siemens SIRIUS 3RV2011-0KA25 motor protection circuit breaker.
