Power switch 4P, 50kA, TM EB2 400/4S 400A 4P release 004671104

Reliable circuit protection with EB2 power switch

This four-pole power switch with a rated current of 400A and a short-circuit breaking capacity of 50kA is a solid solution for protecting electrical installations. Manufactured by ETI, it is suitable for protecting cables and power supply lines, as well as motors and electrical equipment, against the effects of overloads and short circuits. Its design allows for permanent mounting, ensuring stability and long-lasting protection.

Functionality and flexibility

The EB2 switch offers a wide range of thermal protection current adjustment (252…400A) and short-circuit release settings (2400…4800A), allowing for precise adaptation to the specifics of the protected installation. The adjustment possibilities allow for optimal operation in various working conditions. Additionally, the optional motor drive expands the functionality of the device, enabling remote control. The trip indicator informs about the operation of the protection, facilitating fault diagnosis.

Mounting and compatibility

The switch has a screw connection of the main contacts, which ensures a secure and durable connection of the wires. Numerous additional accessories – overcurrent releases, undervoltage releases, auxiliary contacts or mechanical locks – are available, which increase the possibilities of adaptation to specific needs. The power supply can be connected from any side without changing the technical parameters. The degree of protection IP20 provides basic protection against touch and ingress of solid objects. The device complies with the PN-EN 60947-2 standard, which guarantees its safety and reliability.
