Power switch 4P, 25kA, TM EB2 400/4L 400A 4P release 004671094

4-pole power switch with a rated current of 400A is a reliable protection for electrical installations, designed for both domestic and industrial applications. The device effectively protects circuits against overloads and short circuits, ensuring safe use and long-term operation of equipment. The short-circuit capacity of 25kA guarantees effective disconnection in the event of serious disturbances.

Characteristics and application

This compact EB2 series power switch from ETI is a versatile solution for installers and end-users. It is used to connect circuits and protect cables, power cords, motors and electrical equipment. The adjustable setting range of the overload release (252…400A) and short-circuit release (2400…4800A) allows for precise adaptation to the specifics of the protected installation. The switch is permanently mounted and has a lever for manual control. The tripping indicator informs about the operation of the protection, facilitating diagnosis of problems.

Construction and functionality

The construction of the switch ensures high reliability and durability. Screw connection of the main contacts guarantees a secure and stable connection of the wires. The degree of protection IP20 protects against accidental contact, and the possibility of mounting additional accessories (overcurrent releases, motor drives, auxiliary contacts) expands the functionality of the device. The possibility of remote control using motor drives increases comfort in more advanced systems. The switch has a universal power supply – connection can be made from any side without changing the technical parameters.
