## Long description

Legrand TX3 miniature circuit breaker Type D, rated for 25 A, is designed to protect electrical circuits in 240–415 V AC systems at 50/60 Hz. The device provides overcurrent and short-circuit protection in a compact DIN-rail housing with IP20 protection. Its single-pole configuration and Type D tripping characteristic make it suitable for circuits with moderate inrush currents, while the small footprint (17.8 mm width) helps conserve space in residential and light commercial distribution boards.
Advantages
The TX3 breaker offers reliable overcurrent and short-circuit interruption with a standardized Type D curve that responds appropriately to high inrush currents. Its compact dimensions and DIN-rail mounting simplify installation in crowded panels. IP20 protection ensures basic finger-safe contact protection in typical indoor electrical enclosures. Manufactured by Legrand, the unit follows common quality and compatibility standards for modular distribution products.
Suitable for (tasks / use cases)
Protection of individual branch circuits in homes and apartments
Protection of single-phase loads with significant starting currents (motors, transformers, fluorescent lighting)
Use in small commercial or light industrial distribution boards
Replacement or upgrade of existing miniature circuit breakers with similar specifications

How to use
Mount the breaker on a standard DIN-rail inside a compatible distribution board, ensuring the panel is de-energized before installation. Connect the supply conductor to the input terminal and the load conductor to the output terminal, observing correct polarity and tightening torque as specified by the installation standard. After mechanical and electrical connections are verified, restore power and test the circuit under normal load to confirm correct operation. Follow local electrical codes and safety procedures during installation and commissioning.
Usage recommendations
Choose this Type D 25 A breaker where circuits include devices with moderate to high inrush currents; verify coordination with upstream protection and ensure enclosure accessibility for maintenance. For environments requiring higher ingress protection or multi-pole protection, select a device with an appropriate IP rating or pole count.
