Circuit breaker Legrand Tx3 LS C6A 1P 6kA M 403430

Legrand Tx3 LS C6A 1P 6kA M is a single-pole miniature circuit breaker intended for overcurrent protection in electrical installations. With a C-type tripping characteristic and a rated current of 6 A, this breaker combines selective response to short-circuit currents with thermal overload protection for branch circuits. It has a breaking capacity of 6 kA and is designed for modular DIN-rail mounting in distribution boards and consumer units for residential and light commercial use.

Advantages

The device offers reliable interruption of fault currents up to 6 kA and stable thermal protection for continuous loads near its rated current. Its single-pole configuration and compact modular footprint allow space-efficient installation in standard DIN-rail distribution panels. The C-type curve provides a balance between immunity to harmless inrush currents and prompt tripping for true overloads and short circuits. The breaker is compatible with common mounting accessories and complies with typical safety and performance expectations for miniature circuit breakers.

Suitable for

• Protection of lighting and socket circuits in homes and apartments
• Overcurrent protection for small commercial and retail electrical circuits
• Modular DIN-rail distribution boards in residential renovation projects
• Branch-circuit protection feeding motors or equipment with moderate inrush currents

Key specifications

• Poles: single-pole (1P)
• Tripping characteristic: C curve
• Rated current: 6 A
• Breaking capacity: 6 kA
• Mounting: modular DIN-rail
• Application: overcurrent protection against overloads and short circuits

How to use

Install the breaker into a compatible DIN-rail distribution board following local electrical codes and the panel manufacturer's instructions. Ensure supply and load conductors are correctly connected to the line and load terminals and tightened to the recommended torque. Verify that the breaker's rated current and C-type characteristic match the circuit requirements, then switch the device to the ON position. Periodically test the installation by switching the breaker to OFF and back to ON and inspect for signs of overheating, corrosion, or loose connections.

Usage recommendations

Choose this C6A breaker where a 6 ampere rating with C-curve behavior is appropriate; avoid using it on circuits that require different time-current characteristics or higher breaking capacity. For safety, have a qualified electrician perform installation and any modifications to the distribution board.
