Siemens RHVMS24 Rotary Operator Extension Shaft is a 24-inch extension shaft designed for use with Siemens door-mounted rotary operators on VL-frame molded-case circuit breakers. This part is sold as extension shaft only, intended to increase the actuation reach of the door-coupling rotary mechanism in panels that require longer travel. It is documented as RHVMS24 among Siemens VL external accessories (alongside shorter RHVMS02, RHVMS12, and RHVMS16 variants), with the 24-inch length specified for extended reach.
