Siemens RHVMS24 Rotary Operator Extension Shaft

Siemens RHVMS24 Rotary Operator Extension Shaft is a 24‑inch extension shaft designed to extend the reach of a door‑mounted rotary operator for Siemens molded‑case circuit breakers. Sold as an extension shaft only, it is part of the RHVMS family of shaft extensions and is intended to be paired with the corresponding door‑mounted rotary operator kit to actuate breaker handles from outside the enclosure. The 24‑inch length is chosen for installations where the breaker is recessed or obstructed, allowing manual operation without reaching deep into the cabinet. The RHVMS24, along with RHVMS02, RHVMS12, and RHVMS16 variants, provides different reach options within the same family to accommodate varied cabinet depths and mounting configurations. As an OEM Siemens accessory, it is designed to integrate with Siemens door‑mounted operator hardware for molded‑case breakers, and it does not include the operator hardware itself; compatibility should be verified with the specific breaker series and enclosure in use. This extension shaft is suitable for retrofit or new installations where extended actuation is required to operate the breaker handle from a convenient exterior location.
