## Summary description

Legrand TX3 miniature circuit breaker model 403356 is a 1-pole B13A thermal‑magnetic overcurrent protection device with a 6 kA breaking capacity. Designed for residential and light commercial electrical distribution, it provides short‑circuit and overload protection for circuits with B characteristic tripping. Suitable for mounting in modular DIN-rail panels.

## Long description

The Legrand TX3 1-pole thermal-magnetic circuit breaker B13A with 6 kA breaking capacity is intended for overcurrent protection in residential and light commercial electrical installations. This modular device features a B trip curve suited to protect general-purpose circuits and connected equipment from overloads and short circuits. It is designed for DIN-rail mounting in distribution boards and offers a compact footprint typical for the TX3 series.
Advantages
The TX3 B13A combines thermal and magnetic trip elements to provide reliable overload and short-circuit protection while allowing selective tripping behavior for moderate inrush currents. Its 6 kA interrupting capacity ensures the device can safely clear common fault levels in domestic and small commercial networks. The single-pole design simplifies installation for single-phase circuits and keeps the distribution board layout compact.
Suitable for
Protection of lighting circuits and general-purpose sockets in homes
Overload and short-circuit protection in small offices and retail premises
Installation on standard DIN-rail distribution boards
Circuits with typical inrush current profiles where a B characteristic is appropriate
When it may not be suitable
This 1-pole B13A breaker is not intended for three-phase power distribution or for circuits that require higher breaking capacities than 6 kA. It may not be appropriate for motor protection or heavy inductive loads that need C or D trip characteristics or dedicated motor-protective devices. For applications requiring selective coordination with higher-rated upstream devices, consult an electrical professional to confirm suitability.
Key specifications
Poles: 1
Tripping characteristic: B (thermal-magnetic)
Rated current: 13 A
Breaking capacity: 6 kA
Mounting: DIN-rail compatible modular housing
Application: residential and light commercial single-phase circuits
How to use
Install the circuit breaker on a standard DIN-rail inside a distribution board following local electrical codes. Connect the line conductor to the breaker input and the load conductor to the breaker output, ensuring secure tightening of terminals to the manufacturer’s recommended torque. Use the breaker to protect a single-phase circuit; toggle the manual lever to switch the circuit on or off and rely on automatic trip operation to interrupt the circuit under sustained overload or short-circuit conditions. After tripping, identify and clear the fault before resetting the breaker.
What to consider before purchase
Confirm that a B-type tripping curve and 13 A rating match the protected circuit’s load and inrush characteristics
Check that a 6 kA interrupting capacity is sufficient for the installation’s prospective fault current
Ensure compatibility with the distribution board’s DIN-rail mounting and available space
Usage recommendations
For reliable protection, pair the TX3 B13A with appropriately rated upstream devices and perform periodic visual checks of connections and operation. Have a qualified electrician verify coordination and installation according to local regulations.
