Isolating switch FR 301 63A 1P 406421

Isolator – safety and installation control

The FR 301 63A 1P isolator is a reliable device used to safely disconnect electrical circuits. It finds application in both domestic and industrial installations, providing effective isolation and the possibility of performing maintenance work. The device's fixed mounting design guarantees stability and long-term functionality.

Features and application

This single-pole isolator with a rated current of 63A is designed for mounting in distribution boards. It performs the function of a main and safety isolator, allowing the power to be disconnected to protect people and equipment. The locking mechanism used provides additional protection against accidental switching on during service work. Thanks to the screw connection of the main contacts, installation is simple and intuitive. The device is characterized by high resistance to mechanical damage (IP20) and is adapted to work in a wide temperature range.

• Safety first: The safety isolator function provides effective protection against electric shock during maintenance or repair.
• Versatility: The possibility of use as a main isolator allows for central power disconnection if necessary.
• Durability: The solid construction of the fixed-mounted device guarantees long-lasting and trouble-free operation.
• Easy installation: Screw connection of the main contacts facilitates installation and connection of wires.
• High resistance: The IP20 degree of protection protects against accidental contact and protects against the influence of the external environment.
• Short-circuit protection: The rated conditional short-circuit current of 4500 kA provides protection for the installation in the event of a short circuit.
