## Summary description

Three-pole Legrand Tx3 circuit breaker, B16A rated current, 10 kA breaking capacity (MPN 404126). Designed for protection of three-phase electrical circuits against overloads and short circuits. Compact modular design for DIN-rail mounting in distribution boards. Suitable for residential and light commercial installations requiring reliable overcurrent protection.

## Long description

Three-pole Legrand Tx3 B16A circuit breaker provides overcurrent protection for three-phase electrical circuits. Designed for installation on a standard DIN rail in distribution boards, this modular device interrupts fault currents up to 10 kA and protects installations from overloads and short circuits. The compact design and standardized dimensions make it suitable for residential and light commercial electrical panels where selective protection and reliable switching are required.
Advantages
The Legrand Tx3 B16A 3P circuit breaker features a B-type tripping curve that ensures dependable protection for circuits with predominantly resistive loads and low inrush currents. Its 10 kA breaking capacity meets common safety requirements for many building installations, and the three-pole configuration allows simultaneous disconnection of all phases to prevent unsafe phase-to-phase conditions. The modular form factor and DIN-rail mounting simplify wiring and panel layout while maintaining compatibility with standard accessories and busbar systems.
Suitable for (tasks / use cases)
 Protection of three-phase lighting and socket circuits in homes and apartments
 Overcurrent protection for small commercial units and office distribution boards
 Safeguarding motors and distribution circuits with low to moderate inrush currents
 Integration into modular panels and consumer units requiring coordinated protection
Key specifications
 Poles: 3-pole simultaneous disconnection
 Rated current: 16 A (B characteristic)
 Breaking capacity: 10 kA
 Mounting: DIN-rail modular design for distribution boards
 Tripping curve: B-type (suitable for resistive loads and moderate inrush)
 Application: Three-phase AC circuits
 Form factor: Compact modular circuit breaker for panel installation
How to use
Install the circuit breaker on a compatible DIN rail inside the distribution board, following local electrical codes and safety practices. Connect the three incoming phase conductors to the line terminals and the outgoing phase conductors to the load terminals, ensuring tight and secure connections. Verify that the device is the correct type and rated current for the circuit being protected. After installation, switch the breaker to the ON position to restore power; in the event of an overload or short circuit the breaker will trip automatically and can be manually reset after the fault is cleared.
Usage recommendations
Use this Legrand Tx3 B16A 3-pole breaker for circuits with mainly resistive loads or equipment with low starting currents. Coordinate selection with upstream and downstream protective devices to ensure selectivity and avoid nuisance tripping. Periodically inspect connections for tightness and signs of overheating, and ensure the distribution board provides adequate ventilation and labeling for maintenance and safety.
