Legrand TX3 interruttore automatico interruttore automatico miniaturizzato tipo C 3

Legrand Tx3 LS C32A is a 3-pole circuit breaker rated for 32 A and a 6 kA prospective short-circuit breaking capacity. Designed for protection of three-phase electrical circuits, this modular device interrupts overloads and short circuits to safeguard wiring and connected equipment. The compact form factor and standardized mounting make it suitable for installation in residential and light-industrial distribution boards where three-pole protection is required.

Advantages

The circuit breaker offers stable thermal-magnetic tripping characteristics for reliable overload and short-circuit protection. Its three-pole design enables simultaneous switching of all phases to maintain balanced protection in three-phase systems. The device is built to fit standard DIN-rail panels and provides clear current rating and trip type marking for easy identification during installation and maintenance.

Key specifications

How to use

Install the circuit breaker on a compatible DIN-rail inside the distribution board, ensuring the supply and load conductors are connected to the correct terminals and tightened to the manufacturer's recommended torque. Verify the panel is de-energized before making connections. After installation, switch the breaker on and test the protected circuit under controlled conditions to confirm correct operation. For load balancing in three-phase systems, ensure all phases are connected consistently and that upstream protection coordination is maintained.

Recommendations

Use the breaker within its rated current and breaking capacity limits. Periodically inspect connections for signs of heating or corrosion and retighten terminals if necessary after initial load-in. Coordinate the device with upstream and downstream protective equipment to ensure selectivity and minimize unnecessary outages.
