TX3 4P 10A Circuit Breaker Curve C Curve C 6kA

The Legrand TX³ 4P 10 amp circuit breaker, reference 403625, is a four-pole automatic circuit breaker designed to protect electrical installations against overloads and short circuits. It also enables circuit control, isolation, and disconnection functions.

Part of the Legrand TX³ range, it features 4 protected poles, a rated current of 10 amps, a rated voltage of 400 volts AC, and a Type C tripping curve. Its breaking capacity reaches 6 kA at 400 volts, providing a suitable solution for distribution boards in residential, commercial, and other electrical distribution applications.

Protection against overloads and short circuits

This thermal-magnetic circuit breaker combines thermal protection against overloads and magnetic protection against short circuits. In this way, it automatically cuts off the supply when the current exceeds permissible values, helping protect conductors and equipment connected to the installation.

Its C tripping curve sets an instantaneous magnetic threshold between 5 and 10 times the rated current. For this 10 amp model, magnetic tripping in the event of a short circuit occurs within a range of 50 to 100 amps.

Four-pole circuit breaker for three-phase installations

The Legrand 403625 has 4 total poles and 4 protected poles, allowing simultaneous disconnection of the installation conductors. Its four-pole configuration is especially suitable for three-phase circuits with neutral where joint switching is required.

The device operates at a rated voltage of 400 volts and supports an operating frequency of 50 to 60 hertz.

6 kA breaking capacity

The TX³ circuit breaker offers a rated breaking capacity Icn of 6 kA at 400 volts according to EN 60898-1. At 230 volts, its rated breaking capacity reaches 10 kA.

The breaking capacity allows the device to safely interrupt high short-circuit currents within the values established for the product.

Modular DIN rail mounting

The circuit breaker is designed for installation on a DIN rail inside electrical panels. It occupies 4 modules, making it easy to integrate alongside other modular protection, control, and command devices.

It has an installation depth of 44 millimeters and an IP20 protection rating against contact with internal parts once installed in accordance with the manufacturer's instructions.

Safe and flexible connection

The circuit breaker can be supplied from either the top or bottom using copper conductor or a compatible connection comb, providing greater flexibility during panel assembly.

Its terminals accept conductors up to 25 square millimeters for flexible cable and up to 35 square millimeters for rigid conductor. The connection is protected against direct contact and features screws designed to make wiring easier.

Easy circuit identification

The Legrand TX³ includes label holders, allowing the protected circuit to be clearly identified inside the electrical panel. This feature makes installation, maintenance, and circuit tracing easier.

In addition, the circuit breaker can be complemented with certain Legrand DX³ range accessories and auxiliaries, expanding control and signaling options according to the needs of the installation.
