27990021-SOCO

Overview

The Socomec 27990021 is an auxiliary contact kit designed for SIRCO switch-disconnector bodies ranging from 100A to 600A. It features a front-mount configuration with one normally open (NO) and one normally closed (NC) contact. The contacts are rated for 10A at 125 VAC. This component provides pre-break information and monitors the position of the switch disconnector, ensuring safe operation in industrial power applications.

Feature Summary

• Provides pre-break auxiliary signals for enhanced operational safety
• Monitors switch disconnector position accurately
• Designed for front-mount installation on compatible switch bodies

Applications

• Industrial power distribution systems
• Switch-disconnector monitoring circuits
• Safety interlock implementations

Procurement Notes
