It features an EMERGENCY-OFF design with a red/yellow actuator, allowing a panel door to be closed while the breaker handle is operated from outside the enclosure. This part is in product phase-out. The preferred successor is the 3RV2946-2C, which has a different drilling pattern, so a panel modification is required when swapping. Mounts via screw fixing in any position. The operating mechanism is rated for up to 151 operations per hour and operates across -20 to +70 °C, with a storage range of -50 to +80 °C. Dimensions are 75 mm wide, 75 mm high, and 78 mm deep, with a 300 mm length and 40 mm diameter for the shaft/coupling assembly.","metaTitle":"Siemens 3RV1946-2C SIRIUS Door-Coupling Rotary Operator, EME","metaDescription":"Siemens SIRIUS 3RV1946-2C door-coupling rotary operating mechanism for circuit breaker size S3.
