Insulating disconnect switch, fuse-rated, single-pole, R 301 63A 606609

Isolator switch – safety and reliability in your installation

This single-pole fuse isolator switch R 301 63A is a key element ensuring safe and efficient disconnection of electrical circuits. It will work both in home and industrial installations where reliable protection against overloads and short circuits is required. The device's design allows for indirect mounting and in distribution boards, providing flexibility during installation.

Functionality and technical parameters

The isolator is characterized by a high switching capacity at 400V, amounting to 25.2 kW, which allows it to handle loads with significant power. The rated short-time withstand current Icw at 50 kA guarantees effective protection in the event of sudden overvoltages. The device has a locking mechanism that prevents accidental disconnection of the circuit, increasing safety. Made of high-quality materials, it ensures durability and resistance to environmental conditions. The IP40 protection class protects against the ingress of solid objects larger than 1mm, which is important in industrial and workshop environments.

Installation and application

The installation of the isolator is simple and intuitive thanks to the screw connections of the main contacts. The device is intended for permanent mounting, which ensures stability and reliability of connections. As a main switch, it allows for complete isolation of the circuit from the power supply during maintenance or repair work. The rated operating voltage in the range of 12…400 V and the maximum operating voltage Ue AC of 400 V make the isolator universal and can be used in various types of electrical installations. The rated continuous current Iu is 63 A, and for AC-21 at 400V – 63 A, which confirms its efficiency and reliability in everyday use.
