Disconnect switch On/Off In=63A P=37kW P3-63/I4/SVB/N 207349

Main and isolating switch – reliable power disconnection

This switch, with a rated current of 63A and a power of 37kW, is a solid solution for safely disconnecting electrical circuits. It can be used as a main switch for the installation or as an isolating switch, providing full control over the power supply. The device's design, compliant with IEC/EN 60947-3 standards, guarantees high reliability and safety of use.

Functionality and application

The device combines the functions of a main switch, a safety switch, and a maintenance switch. This makes it versatile and can be used in various applications – from securing installations in residential and commercial buildings to ensuring safe disconnection of equipment during maintenance work. A red handle with a yellow locking ring (can be locked with 3 padlocks) further enhances safety, preventing accidental switching on of the device during service work.

Construction features and mounting

The P3-63/I4/SVB/N switch is characterized by its compact dimensions (160 mm wide, 180 mm high, and 139 mm deep) and solid construction. It is a complete device in an enclosure, designed for plate mounting or indirect mounting. Screw connection of the main contacts ensures secure and durable electrical connections. The IP65 protection rating on the front side guarantees resistance to dust and moisture, allowing it to be used in harsh environmental conditions. The built-in locking mechanism increases safety. Rotary drive on the door provides convenient operation. It is designed to operate with a rated voltage of 690…690 V and has a switching capacity at 400 V of 30 kW. The rated short-circuit withstand current Icw is 1.26 kA and the conditional short-circuit current Iq is as high as 100 kA.
