Siemens CFSS10400HN Heavy Duty Shaft 10 X 400

Product Description

The SIEMENS CFSS10400HN is a heavy duty shaft designed for use in electrical enclosure and breaker applications where a robust, reliable actuator component is required. This shaft provides the mechanical interface needed to operate disconnect or rotary switching mechanisms from outside an enclosure panel. At 0.683 pounds and compact packaged dimensions, it is a straightforward replacement or new-installation component handled by licensed electricians during panel assembly or service work.

This shaft is suited for commercial and industrial electrical installations where rotary operators or handle mechanisms must engage internal breaker or disconnect components through an enclosure door or cover. It is typically installed during initial panel builds or as a replacement when an existing shaft shows wear or damage. Electricians working on enclosed motor control centers, panelboards, or switchgear assemblies are the primary installers of this component.

Key Features

• Heavy duty construction for reliable mechanical actuation in enclosure applications
• Compact form factor fits standard rotary operator assemblies
• Lightweight at 0.683 pounds for easy handling during panel work
• Designed for consistent engagement with internal switching or disconnect mechanisms

Compatibility

Designed as an OEM-style replacement shaft for use with compatible SIEMENS rotary operator and enclosure handle assemblies. Refer to SIEMENS documentation to confirm fitment for your specific enclosure or breaker configuration.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the panel or enclosure before removing or installing any shaft or actuator components. Verify that the shaft engages the internal mechanism fully and rotates freely before closing and re-energizing the enclosure. Do not force the shaft into position, as misalignment can damage internal breaker or disconnect components.
