Isolating switch FR 302 63A 2P 406447

Isolator – safety and reliability in your installation

This two-pole FR 302 isolator with a rated current of 63A is a key element of any electrical installation, providing effective protection against overload and short circuit. It is a device designed to safely disconnect circuits, both in domestic and industrial installations. Thanks to its solid construction and high-quality workmanship, it guarantees long-lasting and trouble-free operation.

Functionality and application

The FR 302 isolator is designed for mounting on a TH35 rail, making it easy to integrate with existing distribution boards. Its compact size – only 2 modules wide – allows for efficient use of space. The device meets the requirements of operating category AC 22A according to IEC/EN 60947-3, which confirms its reliability in various applications. The possibility of connecting an auxiliary contact (ref. no. 406250) expands the functionality of the device, enabling remote monitoring of the circuit status.

• Versatile application: ideal for installation in residential, commercial and industrial buildings.
• Safe disconnection: allows for quick and safe disconnection of the circuit in the event of a failure or the need to perform maintenance work.
• Easy installation: thanks to standard dimensions and the possibility of mounting on a TH35 rail, installation is simple and intuitive.
• High short-circuit strength: short-circuit current up to 4500 kA provides protection against the effects of sudden overvoltages.
• Locking mechanism: prevents accidental opening of the isolator during operation, increasing safety.

Construction and parameters

The FR 302 isolator is characterized by a solid construction of a fixed device and a screw connection of the main contacts, which ensures a secure and durable connection of the wires. The degree of protection IP20 protects against finger contact and the ingress of solid objects larger than 12.5 mm. The rated operating voltage is from 0 to 690 V, and the maximum AC voltage is 400 V, making it a universal solution for various types of installations. The grey lever makes it easy to identify and operate the device.
