Isolation Switch Legrand FR 302 2P 40A (MPN 406446)

Legrand FR 302 is a 2-pole isolation switch rated for 40 A, designed to provide a reliable means of manually disconnecting electrical supply for maintenance, repair, or emergency procedures. The device delivers a clear physical separation of live conductors, helping to ensure that circuits remain de-energised while work is carried out. Its compact design and straightforward operation make it suitable for use in residential and light-commercial electrical installations.

Advantages

The isolation switch offers a durable mechanical design with stable contact operation and a visible disconnect position to confirm circuit separation. It is rated for 40 A across two poles, enabling reliable interruption of single-phase circuits where both line and neutral require isolation. The manual actuator is simple to operate and provides tactile feedback, while robust construction supports repeated switching during maintenance cycles.

Suitable for

• Isolating lighting and power circuits in homes and apartments
• Disconnecting small commercial or office electrical loads for safe maintenance
• Temporary isolation during testing, inspection, or component replacement
• Service panels and distribution boards requiring a local means of disconnection

Key specifications

• Number of poles: 2-pole isolation
• Rated current: 40 A
• Function: Manual electrical isolation / disconnection
• Application: Residential and light-commercial circuits
• Operation: Toggle/manual actuator with visible disconnect indication

How to use

Install the isolation switch into the enclosure or mounting location following local electrical codes and standard wiring practices. Connect supply and load conductors to the appropriate terminals, ensuring correct tightening of terminal screws and secure conductor insulation. To isolate a circuit, move the actuator to the OFF position until the visible disconnect confirms separation; to restore supply, move the actuator to the ON position. Always verify absence of voltage with appropriate testing equipment before beginning any work on the isolated circuit.

Usage recommendations

Ensure installation and maintenance are performed by a qualified electrician. Verify compatibility with system voltage and protective devices; use this isolation switch as part of a broader safety procedure that includes lockout-tagout where required. Periodically inspect terminals and mechanical operation for signs of wear or corrosion and tighten connections as necessary to maintain safe operation.
