Legrand TX3 circuit breaker Miniature circuit breaker Type C 1

LEGRAND 403436 TX3 LS C25A 1p 6kA is a single-pole miniature circuit breaker for overcurrent and short-circuit protection in residential and light commercial electrical installations. Part of the TX3 range, this C25A device provides thermal-magnetic protection for circuits up to 25 A while occupying a single module width on standard DIN rails.

Advantages

The LEGRAND TX3 LS C25A offers accurate thermal-magnetic tripping to protect against overloads and short circuits, with a 6 kA breaking capacity for improved fault interruption. Its single-pole design simplifies wiring for individual circuits, and the 1M width allows efficient use of distribution board space. Compatibility with DIN-rail systems and TX3 accessories ensures straightforward installation and replacement.

How to use

Switch off the supply before installation. Mount the LEGRAND TX3 LS C25A onto a standard DIN rail in the distribution board and secure it according to the manufacturer's mounting instructions. Connect the phase conductor to the input terminal and the load conductor to the output terminal, observing polarity and local electrical codes. Tighten terminals to the recommended torque, restore supply, and operate the breaker manually to confirm correct switching. If the device fails to operate as expected during testing, replace it.

Recommendations

Use this single-pole 25 A breaker for individual circuit protection such as lighting or socket circuits; verify panel space and coordination with upstream and downstream protective devices before installation.
