## Long description

Legrand TX3 Type C miniature circuit breaker, 3-pole, rated for 40 A, provides protection for electrical circuits in residential and light commercial distribution boards. It is designed for systems with supply voltage from 240 to 415 V and frequency 50–60 Hz. The breaker has an IP20 enclosure rating and compact dimensions (53.1 mm width, 77.8 mm depth, 88 mm height), enabling installation in standard DIN rail panels to protect against overloads and short circuits.
Advantages
The device combines a Type C tripping characteristic, suitable for general-purpose circuits, with a 3-pole configuration to protect three-phase or multi-pole circuits uniformly. Its compact form factor saves space in distribution enclosures, while the IP20 rating protects internal components from accidental contact. The Legrand TX3 range is known for consistent mechanical and electrical performance, supporting reliable disconnection and repeatable operation under expected load and fault conditions.
Suitable for
Protection of lighting and socket circuits in homes and apartments
Protection of small motor loads and HVAC equipment in light commercial settings
Three-phase sub-circuits in small distribution boards
General circuit protection in renovation and new-build electrical installations

How to use
Install the breaker on a standard DIN rail inside the distribution board following local electrical codes and manufacturer installation instructions. Ensure the supply is isolated before wiring. Connect phase conductors to the line terminals and load conductors to the load terminals, observing correct tightening torque for secure connections. After wiring, restore supply and verify correct operation by switching the breaker on and off and by checking circuit continuity and absence of unwanted tripping under normal load.
Usage recommendations
Match the breaker rating and tripping characteristic to the protected circuit and connected equipment. Use this Type C breaker for circuits with moderate inrush currents; for high inrush motor-start circuits consider a different characteristic. Periodically inspect terminals for tightness and signs of overheating, and replace the device if mechanical or electrical performance degrades.
