Siemens RHVMS16 Variable Length Shaft Vl Breakers

Product Description

The SIEMENS RHVMS16 is a variable-length rotary operator shaft designed for use with VL-series molded case circuit breakers. This mechanical accessory allows field technicians to adjust the shaft length to match the depth of the enclosure or operator mechanism, ensuring proper alignment between the external rotary handle operator and the breaker toggle. It is a hardware-level component installed by licensed electricians during panel or switchgear commissioning or when upgrading existing breaker operator assemblies. The part weighs 0.22 pounds and measures approximately 16.5 inches in length, making it compatible with standard rotary operator mounting depths used in industrial and commercial electrical distribution equipment.

The RHVMS16 is used in commercial and industrial electrical installations where VL-series molded case circuit breakers require external rotary operator handles. Typical applications include motor control centers, distribution panels, and switchgear enclosures where through-door handle operation is required. The variable-length design accommodates varying door thicknesses and mounting configurations without requiring a custom-machined shaft or additional adapter hardware.

Key Features

• Variable-length shaft accommodates different enclosure door depths and operator mounting configurations
• Designed for use with Siemens VL-series molded case circuit breakers
• Lightweight construction at 0.22 pounds for easy handling during installation
• 16.5-inch overall length provides range for standard commercial and industrial enclosure depths
• Enables through-door rotary handle operation without internal panel access

Compatibility

Designed as an OEM-style rotary operator shaft accessory for Siemens VL-series molded case circuit breakers used in commercial and industrial electrical distribution applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify absence of voltage before working on any breaker operator assembly. Confirm shaft length adjustment and operator alignment before securing all fasteners to ensure reliable breaker actuation. Do not modify or cut the shaft beyond the manufacturer-specified adjustment range.
