Product information

Description

LEGRAND 403404 TX3 LS B25A 3p 6kA 3M is a three-pole miniature circuit breaker rated 25 A with a type B tripping characteristic, intended for protection of electrical circuits against overloads and short circuits. The device is part of the TX3 range, has a 3-module width for compact installation on a standard DIN rail, and a rated breaking capacity of 6 kA suitable for typical residential and light commercial distribution boards.

Advantages

The LEGRAND TX3 LS B25A provides clear and consistent protection with a defined B25A rating for circuits that require a type B characteristic. Its three-pole design ensures simultaneous disconnection of all phases, reducing the risk of unbalanced phase conditions. The 3M width allows space-efficient mounting in distribution panels, and the 6 kA breaking capacity delivers reliable interruption of fault currents within the device's rated limits.

Suitable for

Protection of three-phase branch circuits in residential and light commercial installations
Installation in compact distribution boards where a 3-module breaker is required
Circuits with load characteristics compatible with a type B, 25 A breaker
