Product information

Description

Legrand FRX 403 is a 3-pole isolation switch rated for 125 A, designed to provide reliable mechanical disconnection of three-phase electrical circuits. It is intended for use in distribution boards, switchboards and electrical panels where a clearly visible and manually operated disconnect is required for safe maintenance, emergency isolation and equipment protection. The robust construction ensures stable operation under normal industrial and commercial conditions.

Advantages

The switch offers simple manual operation with positive open and closed positions, ensuring clear indication of circuit status. Its 3-pole design enables simultaneous disconnection of all phases, reducing the risk of dangerous backfeed during service. The device is compact enough for panel integration while providing a rated current capability suitable for many commercial and light industrial electrical installations.

Suitable for

  • Manual disconnection of three-phase circuits in distribution boards and switchboards
  • Safe isolation for maintenance and repair work
  • Emergency isolation to protect personnel and equipment
  • Installation in commercial buildings, small workshops and light industrial sites

Key specifications

  • Configuration: 3-pole mechanical isolation switch
  • Rated current: 125 A
  • Function: manual on/off isolation with visible contact position
  • Intended use: three-phase circuits
  • Mounting: panel or switchboard installation

How to use

Install the isolation switch in accordance with local electrical codes and the panel manufacturer’s instructions, ensuring appropriate conductor sizes and secure terminal connections for 125 A operation. Before performing maintenance, switch the device to the off (open) position and verify the absence of voltage with a suitable tester. Lock-out/tag-out measures can be applied to the handle where required to prevent accidental re-closure during work.

Usage recommendations

Use appropriate torque settings for terminal screws and confirm that cables and lugs are rated for the switch’s current. Periodically inspect the handle movement and terminal tightness, and verify operation under no-load conditions after installation. For environments with specific temperature, humidity or ingress protection requirements, select compatible panel enclosures and follow Legrand guidance for safe installation.
