Disconnect switch FRX 303 63A 3P 406536

Isolator switch – reliable power disconnection

The FRX 303 63A 3P isolator switch is a key element of any electrical installation, providing safe and reliable disconnection of circuits. Designed for mounting in distribution boards, it enables effective isolation and protection against accidental switching on during maintenance or repair. The device's construction, as a permanently mounted element, guarantees stability and long-term reliability.

Functionality and application

This three-pole (3P) switch with a rated continuous current of 63A is perfect for installations with a voltage of 400V AC. Its main function is to completely isolate the circuit, which is particularly important during service work, modernization or failures. Thanks to the possibility of use as a safety switch and main switch, it provides versatility and flexibility in various applications. The locking mechanism additionally protects against accidental switching on, increasing the level of safety.

Key features and benefits

• Safety first: The safety switch function guarantees complete circuit isolation during maintenance work.
• High short-circuit resistance: Rated conditional short-circuit current Iq at 4500 kA provides protection against the effects of sudden overvoltages.
• Solid connections: Screw connection of the main contacts ensures a secure and durable connection of the wires.
• Versatility: The possibility of using it as a main or safety switch increases the range of applications.
• Durable construction: The permanently mounted device is characterized by high stability and reliability.
• IP20 protection rating: Provides basic protection against accidental contact with live parts.
• Intended for distribution boards: Enables easy integration with existing electrical infrastructure.

The rated operating voltage is 400…400 V, and the rated continuous current (Iu) is 63 A. The device has 3 poles and provides a rated conditional short-circuit current (Iq) of 4500 kA, and the degree of protection (IP) of the front is IP20.

This isolator switch is a solid choice for both professional installers and end users looking for a reliable solution for safely disconnecting power in their electrical installations.
