Legrand TX3 Ochranný istič Miniatúrny ochranný istič Typ C 1

Legrand Tx3 Ls C2A 1P 6kA M is a single-pole miniature circuit breaker designed for overcurrent protection in residential and light commercial installations. With a rated current of 2 A and a C tripping characteristic, this breaker interrupts fault currents up to 6 kA and mounts on an M-frame, offering reliable protection for cables and downstream equipment against short-circuits and overloads.

Advantages

The device combines a compact single-pole form factor with a C characteristic suitable for general-purpose circuits where moderate inrush currents may occur. Its 6 kA breaking capacity meets common installation requirements and helps ensure circuit integrity during short-circuit events. The M-frame mounting compatibility simplifies integration into panels and distribution boards designed for this modular format. The breaker is manufactured by Legrand, a recognized brand in electrical components, and is intended for straightforward replacement or installation in existing systems.

Suitable for

When it may not be suitable

This 2 A single-pole breaker is not suitable for circuits that require higher continuous current ratings or multi-pole protection such as three-phase systems. It is also not appropriate where a higher breaking capacity is mandated by local regulations or where selective coordination with upstream protective devices requires different characteristics.

Key specifications

How to use

Install the breaker into a compatible distribution board or DIN-rail panel with M-frame mounts, ensuring the mains supply is de-energized before work begins. Connect the incoming live conductor to the breaker terminal and the outgoing conductor to the load terminal, tightening terminals to the manufacturer's recommended torque. After installation, restore power and verify correct operation by switching the breaker on and off. Test the circuit under actual load conditions and observe for proper tripping behavior during simulated overloads or short conditions following local safety procedures.

What to consider before purchase

Recommendations

For reliable protection, match the breaker rating to cable ampacity and the expected load. When replacing an existing device, ensure compatibility with the panel's mounting system and verify tight, clean electrical connections. For circuits with motors or high inrush loads, consider whether a different characteristic or higher rating is necessary.
