Isolating switch FR 301 16A 1P 406400

Insulation disconnect switch – reliable circuit disconnection

The FR 301 16A 1P insulation disconnect switch is a device used to safely disconnect electrical circuits. It is a key device in electrical installations, providing the ability to switch off the power for maintenance, repair work or in emergency situations. The device is designed for use in both domestic and industrial installations.

Construction and application

The FR 301 disconnect switch is characterized by a solid construction and durability. It is a permanently mounted device designed for mounting in distribution boards. Its single-pole design makes it ideal for disconnecting individual circuits. The locking mechanism provides additional safety, preventing accidental switching on or off of the disconnect switch during operation. Screw connection of the main contacts guarantees a secure and stable connection of the wires.

The rated continuous current of 16A and the maximum operating voltage of 250V AC make it suitable for protecting various receivers, such as lighting, electrical sockets or small electrical appliances. The rated conditional short-circuit current of 4500 kA indicates its resistance to overloads and short circuits. The IP20 degree of protection provides protection against accidental contact.

Safety and compliance with standards

The FR 301 meets the requirements for safe use and is designed to operate at temperatures from -25°C to 70°C. As a safety and main disconnect switch, it provides effective protection of the electrical installation against overloads and short circuits – like most circuit breakers in this class. Its construction allows for mounting from the top or bottom, which facilitates installation in various configurations of distribution boards. The device has certificates confirming its compliance with applicable standards, which guarantees its reliability and safety of use.
