Power switch 3P, 25kA, TM release (non-adjustable) EB2 400/3LF 400A 3P 004671105

Reliable protection of power circuits and electrical devices

This three-pole EB2 400/3LF 400A power switch is a solid solution for securing electrical installations. It provides effective protection against overloads and short circuits, protecting cables, power cords, motors and other electrical equipment. Its construction, based on proven technology, guarantees reliable operation in demanding conditions. It is ideal for both industrial and commercial installations.

Characteristics and application

The switch is designed for switching circuits and protecting against the effects of overloads and short circuits. The rated continuous current of 400A allows it to be used in circuits with high power consumption. The TM (thermomagnetic) trip characteristic provides a quick response to short circuits, while allowing short-term overloads without unnecessarily disconnecting the circuit – which is particularly important when starting motors or other devices with high starting current. The rated short-circuit breaking capacity of 25kA at 400V guarantees the safety of the installation in the event of serious disturbances.

Construction and mounting

The switch has screw connections, which facilitates mounting and connection of wires. The device is designed for permanent mounting and can be installed in any position – which provides great flexibility when designing switchgear. Thanks to its compact dimensions, it takes up little space in the control cabinet. Additionally, the presence of a trip indicator allows for quick identification of the device status after the protection has operated. The possibility of equipping with a motor drive and additional accessories (auxiliary contacts, alarm contacts) increases the functionality of the switch and adapts it to the specific needs of the installation.
