32A 690V 3-Phase AC-23A Rotary Cam Isolator Switch (EN60947-3)

Description:

This is a rotary cam isolator/changeover switch manufactured by OPAS, designed to manually connect, disconnect, or switch between electrical circuits or power sources in industrial control panels and distribution systems. The switch offers three selectable positions — "1" and "2" for switching between two separate circuits or power sources, and a center "0" position for complete circuit isolation — making it well suited for source-changeover applications such as switching a load between two supply lines, or manually isolating a circuit for maintenance and safety (lockout/tagout) purposes.

Built to IEC 60947-3 standards for low-voltage switchgear, the switch is rated for 32A continuous thermal current and up to 690V insulation voltage, with an AC-23A utilization category rating — meaning it's specifically rated for switching motor loads (not just simple resistive loads), accounting for the higher inrush current motors draw at startup. This makes it suitable for both general power distribution switching and direct motor control applications in 3-phase systems.

The switch features a compact, panel-mount design with a clear white front faceplate and bold black position markings (1-0-2) for easy visual confirmation of the switch state at a glance. A sturdy gray rotary handle with a captive screw provides tactile, positive switching action, while the orange terminal block housing at the rear offers clearly organized screw terminals for secure wiring connections. The switch mounts via a 4-hole front bracket, making it straightforward to install into a standard control panel cutout.
