Siemens 3VL9300-3HE00 Rotary Drive Direct Shaft No Knob Operating Handle

The Siemens 3VL9300-3HE00 is a front-mounted rotary operating mechanism accessory for VL160X, VL160, and VL250 circuit breakers, providing a direct shaft drive with a shaft stub and no knob to enable manual operation through the door. It is designed to work with door coupling components 8UC6262-6BD22 or 8UC6272-8BD22, enabling reliable engagement between the rotary actuator and the breaker door for operation from the front. The unit is listed as an accessory in Siemens Sentron 3VL products and is specifically described as a rotary drive accessory for direct shaft operation with a shaft stub and without knob. The accessory has a net weight of 0.41 kg, and it mounts on the front face of VL series breakers to provide a manual actuation interface without requiring a knob. This no-knob variant is ideal for installations where a knob is unnecessary or where a standard front-mounted rotary operator is required for routine maintenance or testing through the cabinet door.
