Isolating switch FR 303 20A 3P 406457

Isolator switch – reliable disconnection in the installation

This three-pole FR 303 isolator switch with a rated current of 20A is a key element of every safe and functional electrical installation. It will work well in both commercial facilities and residential buildings, providing effective disconnection of circuits. Its compact dimensions (35.6 mm wide) allow for easy mounting in distribution boards, taking up only 2 modules.

Functionality and safety in one device

The FR 303 isolator switch is designed for durability and reliability. Made of high-quality materials, it guarantees long-term use even in demanding conditions. The rated continuous current of 20A and high short-circuit resistance (up to 4500 kA) ensure effective protection of the installation against overloads and failures. The locking mechanism additionally protects against accidental opening of the circuit during operation or maintenance.

• Versatile mounting: Designed for installation in distribution boards, making it easy to integrate with existing infrastructure.
• Safety: Main and safety isolator function provides full control over the circuit and the ability to safely disconnect the power supply if necessary.
• Solid connections: Uses screw connections for the main contacts, guaranteeing stable and reliable connection of wires.
• Wide voltage range: Ability to operate in circuits with a voltage of up to 690V AC (maximum working voltage 400V AC) increases its versatility.
• Durability: The device is permanently mounted, ensuring stability and reliable operation for a long time.

Specification for professionals

The FR 303 isolator switch meets the requirements of IEC/EN 60947-3 standards, confirming its compliance with European safety standards. The IP20 degree of protection provides protection against accidental contact, and the ability to cooperate with comb or pin busbars facilitates quick and efficient installation. Additionally, it is possible to connect an auxiliary contact (ref. no. 406250) to expand the functionality of the device – e.g. remote monitoring of the isolator switch status.
