Main switch disconnector, 3-pole + 1NO + 1NC, 40 A, panel mounting, red-yellow knob with padlockable locking device P1-40/EA/SVB/HI11 199895

Main Disconnector – Reliable Installation Protection

This main disconnector from Eaton is a key element of any electrical installation, providing safe and controlled disconnection of circuits. Designed for panel mounting, it offers a solid construction and functionality, meeting the requirements of both professional installers and end-users. The device is ideal for use in commercial, industrial buildings and in home installations requiring high reliability.

Functionality and technical parameters

The disconnector with a rated current of 40 A, with three poles and one normally open (1NO) and one normally closed (1NC) auxiliary contact, allows for effective disconnection of power when needed. Equipped with a red-yellow knob with a padlock, it provides additional security and prevents accidental switching on or off. The rated operating power for AC-3 is 15 kW at 400 V, and for AC-23 – 22 kW. The device's design allows it to be used as a renovation disconnector and an emergency switch. The IP65 protection class guarantees resistance to dust and moisture, making it suitable for use in harsh environmental conditions.

Installation and application

Panel mounting simplifies the integration of the disconnector with the existing electrical infrastructure. Screw connection of the main contacts ensures secure and durable wire connections. The device is particularly useful in situations requiring manual disconnection of power, e.g. during maintenance, repairs or failures. The locking mechanism in the off position increases work safety. Thanks to its compact dimensions (75 mm depth, 70 mm height, 49 mm width), the disconnector easily integrates with various types of switchboards and control cabinets. The rated withstand current Icw is 0.64 kA and the conditional short-circuit current Iq is 80 kA, providing protection against the effects of short circuits.
