Power switch I-0-II 4P 250A HI454

Power switch – reliable switching in your installation

This four-pole power switch from Hager, with a rated current of 250A, is a solid solution for safe and efficient switching of electrical circuits. Designed for use in both commercial and industrial buildings, it provides reliable operation and long-lasting performance. The device's construction allows for mounting on a plate or in distribution boards, making it easy to integrate with existing infrastructure.

Functionality and application

The HI454 switch allows you to choose between three positions: I (on), 0 (off) and II (second circuit). This makes it ideal as a main switch, safety switch and maintenance switch. The ability to switch between two power sources (position I and II) makes it an excellent choice for emergency power systems or where redundancy is required. Equipped with a long rotary handle, it provides convenient and precise operation. A locking mechanism guarantees safety, preventing accidental repositioning.

Parameters and construction features

The device is characterized by a high switching capacity – up to 164 kW at 400V – and a high short-circuit current Iq of 50 kA. Made of high-quality materials, it ensures durability and resistance to mechanical damage. The IP00 protection class indicates no protection against the ingress of solids or water, so the switch should be mounted in enclosures providing adequate protection. The rated operating power for AC-3 is 132 kW, and for AC-23 – 90 kW, confirming its versatility and applicability in various installations. The rated continuous current Iu is 250A, and the withstand short-circuit current Icw is 15 kA. The device's construction as a permanently mounted element ensures stability and reliable operation for a long time.
