Safely maintain your circuits with this switch disconnector shaft from Eaton. It's designed for use with a UV-P3 isolator device to ensure risk-free operation as you go about your task. This nifty piece of kit comprises a shaft and an interlock extension, which together work by standing between live parts and the rotary handle. It creates a spacing, preventing contact that could lead to an electric shock. For added protection, the plastic housing is a good insulator and won't let any harmful residual current flow through. This kind of component is commonplace in material handling applications.

• Optional assembly on top of three other shafts for a safer distance in volatile applications
• DIN rail-mountable for convenience
• Plastic body holds its own against wear and corrosion for long-lasting performance in harsh environments

None – as it's made of weatherproof material, this unit functions unsupervised without the need for maintenance.

This component is designed as an extension, so to install it, simply plug it into the switch disconnector's shaft socket.
