## Long description

Single-pole Legrand Tx3 circuit breaker 404171 C16A is designed to protect low-voltage electrical circuits against overloads and short circuits in residential and light-commercial installations. The device features a C-characteristic trip curve and a rated current of 16 A, with a breaking capacity of 10 kA. Its compact modular form factor allows DIN-rail mounting for straightforward installation in distribution boards and electrical panels.
Advantages
This Legrand Tx3 circuit breaker offers reliable overcurrent and short-circuit protection with consistent tripping performance thanks to its C-characteristic curve. The 10 kA breaking capacity ensures safe interruption of fault currents typical for small-scale installations. The modular single-pole design saves space inside distribution boards and simplifies wiring and maintenance. Built to standard electrical safety requirements, the unit provides predictable behavior under thermal and magnetic conditions.
Suitable for
 Protection of lighting circuits in homes and apartments
 Protection of socket circuits for general-purpose loads
 Small commercial or office electrical panels
 Retrofit or new installations with DIN-rail distribution boards
Key specifications
 Poles: single-pole (1P)
 Tripping characteristic: C-curve (thermal-magnetic)
 Rated current: 16 A
 Breaking capacity: 10 kA
 Mounting: DIN-rail (modular housing)
 Application: overcurrent and short-circuit protection for low-voltage circuits
How to use
Install the breaker on a standard DIN-rail inside the distribution board and connect the phase conductor to the inlet terminal and the load conductor to the outlet terminal, following local wiring regulations. Ensure correct tightening torque on terminals and verify that the distribution board is de-energized during installation. Use the manual toggle to switch the circuit on and off; the device will trip automatically in the event of an overload or short circuit. After clearing a fault, reset the breaker by moving the toggle to the OFF position and then back to ON as required.
Usage recommendations
Verify compatibility with existing busbar and terminal types prior to installation. Match the breaker’s rated current and C-characteristic to the expected load types—C-curves are suitable for general-purpose circuits with moderate inrush currents, such as lighting and most socket outlets. Periodically inspect connections and operation, and replace the breaker if it shows signs of mechanical damage or repeated nuisance tripping.
