Main disconnector – reliable protection for electrical installations

This three-pole main disconnector from Eaton is a key element of every electrical installation, providing effective isolation and safety. The device is designed for surface mounting and is characterized by high reliability and durability. The lockable design further protects against unauthorized switching, which is particularly important in public places or where additional security is required.

This disconnector is ideal for both commercial buildings and industrial installations. Its solid construction and high resistance to external conditions (IP65 protection) guarantee long-lasting and trouble-free operation. The use of a red-yellow knob with a padlock ensures easy identification of the device status and provides additional safety.

Functionality and technical parameters

The device with a rated current of 40 A allows for safe disconnection of a load of up to 15 kW (AC-3, 400 V) or 22 kW (AC-23, 400 V). Short-circuit strength up to 80 kA protects the installation in the event of a failure. The locking mechanism prevents accidental opening of the disconnector during operation, increasing safety. Screw connection of the main contacts ensures a secure and durable connection of the conductors.

Using this disconnector as an emergency switch allows for quick and safe disconnection of power in critical situations. Additionally, the ability to use it as a repair disconnector facilitates maintenance and repair work without having to shut down the entire installation. The construction of the device as a permanently mounted element ensures stability and reliable operation for a long time. Width 49 mm, height 70 mm and depth 75 mm allow for easy installation even in limited space.
