Isolating switch, fuse-combination unit, three-pole with disconnectable neutral pole, R 323 50A 606758

Fuse isolation switch – reliable installation protection

This three-pole isolation switch with a disconnectable neutral pole, with a current of 50A, is a key element of any electrical installation. Designed to work with D02 fuse links, it provides effective protection against overloads and short circuits. It is a permanently mounted device, intended for installation in distribution boards, which facilitates assembly and ensures tidy wiring.

Functionality and parameters for professionals

The R 323 switch is characterized by a high switching capacity – as much as 20 kW at 400V. Withstand to short-circuit currents at 50 kA guarantees safety even in difficult working conditions. Made of high-quality materials, with a locking mechanism, it ensures reliability and long-term operation. The IP40 degree of protection protects against contact and ingress of solid bodies, which is important in industrial and commercial environments. Screw connection of the main contacts facilitates quick and secure connection of wires.

Safety and ease of use

This switch not only protects the installation, but also allows for safe disconnection of the load during maintenance or repair. Its design allows for easy identification of the status (on/off), and the presence of a disconnectable neutral pole increases the flexibility of the installation configuration. The device meets the required safety standards, which confirms its high quality and reliability. The width of 6 modules (17.5 mm each) allows for efficient use of space in the distribution board.

This switch stands out with a high switching capacity of 20 kW at 400 V, which allows it to handle most standard loads. The rated current of 50 A makes it ideal for protecting circuits with medium power consumption. In addition, high resistance to sudden current surges is ensured by the rated withstand short-circuit current (Icw) of 50 kA. The IP40 degree of protection guarantees protection against contact and ingress of solid bodies, and the disconnectable neutral pole increases the flexibility of the installation and facilitates servicing. The locking mechanism prevents accidental opening of the circuit during operation, and the possibility of mounting in distribution boards and indirect mounting facilitate integration with the existing electrical infrastructure. The device is compatible with readily available D02 fuse links.
