Αυτόματος διακόπτης Legrand Tx3 B32A 6kA 3-πολικός (403405)

Legrand Tx3 LS-Schalter B32A 6kA 3-pole is a compact miniature circuit breaker designed for protection of lighting and power circuits in residential and commercial distribution boards. With a B trip characteristic and a rated current of 32 A, this device provides reliable overcurrent and short-circuit interruption up to 6 kA. Its three-pole configuration enables simultaneous disconnection of all phases, making it suitable for three-phase circuits and modular DIN-rail installation in distribution cabinets.

Advantages

The breaker combines a clear B-type tripping curve with a 32 A rating, offering sensitive protection against moderate inrush currents while ensuring reliable upstream fault clearing. Its 6 kA breaking capacity meets common safety requirements for small installations and provides robust interruption performance for short-circuit events. The three-pole design ensures coordinated phase isolation and simplifies wiring in three-phase systems. The compact modular form factor is compatible with standard DIN-rail mounting and integrates neatly into distribution boards.

Key specifications

How to use

Install the circuit breaker onto a standard DIN-rail inside the distribution cabinet following local electrical codes. Connect the incoming supply conductors to the line terminals and the load conductors to the load side, ensuring correct phase sequence for three-phase systems. Tighten terminals to the manufacturer’s recommended torque values and verify mechanical locking to the rail. After wiring, switch the breaker to the ON position and test the circuit under no-load conditions, then progressively apply load while monitoring for proper operation and absence of nuisance tripping.

Recommendations

Use this breaker in circuits where a B-characteristic is appropriate—typical lighting and general-purpose power circuits with limited inrush currents. Coordinate with upstream and downstream protective devices to ensure selectivity where required, and adhere to local regulations when sizing conductors and protective devices for continual current and fault conditions.
