Main disconnect switch (isolator), 63A, 3-pole HIS-63/3 142822

Main disconnector – reliable power disconnection

This three-pole Eaton HIS-63/3 isolating switch is a key element of any electrical installation, providing safe and reliable disconnection of the circuit. Designed to operate at AC 415V and a rated current of 63A, it is perfect for both domestic and industrial installations. Its compact design (3 module width) makes it easy to mount in distribution boards.

Functionality and safety in one

The HIS-63/3 switch is characterized by a high switching capacity of up to 12.5 kA, which guarantees effective protection against the effects of short circuits. The device's construction ensures forced pole separation, which increases safety during maintenance and repair of the installation. Additionally, the ability to lock with a padlock protects against accidental activation by unauthorized persons. The terminals allow connection of cables with a cross-section of up to 50mm², and the high continuous current of up to 125A provides a power reserve for future needs.

Installation and application

The modular HIS-63/3 switch is easy to mount on a TH35 rail (standard mounting rail). The "arrow" symbol on the housing makes it easy to identify the device's function. The IP40 degree of protection protects against contact with solid foreign objects with a diameter of more than 1mm and against accidental contact with live conductors. The device is ideal for:

• Disconnecting devices during maintenance and repair
• Isolating sections of the electrical installation
• Providing a safe power shutdown in the event of a failure
• Building main disconnection points in distribution boards
• Use in residential, commercial and industrial buildings.

The short-circuit strength (Icw) at 1kA ensures stable operation of the device even in difficult operating conditions. The minimum rated voltage is 240V, and the installation depth is 69.5 mm.
