Disconnect switch FR 304 63A 4P 406487

Isolator switch – safety and control in your installation

This four-pole FR 304 isolator switch with a rated current of 63A is a key element ensuring complete disconnection of power in three-phase installations. It allows for safe isolation of circuits during maintenance, service work, and emergency situations. Ideal for industrial, commercial, and home applications with three-phase power.

Functionality and application

The FR 304 isolator switch is designed for mounting in distribution boards on a 35 mm DIN rail, ensuring easy integration with existing infrastructure. Its fixed mounting design guarantees stability and reliable operation. The ability to connect wires using screw connections ensures a secure and durable connection. The device functions as a main and safety disconnect switch, and the locking mechanism provides additional protection against accidental switching on. The rated continuous current is 63A at a maximum operating voltage of 400V AC, and its short-circuit withstand capacity reaches up to 4500 kA.

Advantages for professionals and end-users
