Product information

Description

Legrand 403546 Tx3 LS-Schalter C20A 6kA 3M is a three-pole miniature circuit breaker designed to protect electrical installations from overloads and short circuits. The device features a C tripping characteristic and a rated current of 20 A, with a breaking capacity of 6 kA. It is built for installation on standard DIN rails and is suitable for use in residential and commercial distribution boards that require three-pole protection.

Advantages

The breaker provides selective and reliable protection with a C characteristic that balances sensitivity to motor startup currents and fast response to short circuits. Its compact 3-module width enables space-efficient installation in distribution panels. With a breaking capacity of 6 kA and proven manufacturing quality, the unit delivers stable performance for typical building electrical circuits. DIN-rail compatibility simplifies mounting and replacement in existing boards.

Suitable for

  • Protection of three-phase circuits in residential buildings
  • Distribution boards in small commercial premises
  • Motor feeder protection where moderate inrush currents occur
  • Retrofit or new installations requiring DIN-rail mounted 3-pole breakers

Key specifications

  • Number of poles: 3
  • Tripping characteristic: C
  • Rated current: 20 A
  • Short-circuit breaking capacity: 6 kA
  • Module width: 3 modules (3M)
  • Mounting: DIN-rail

How to use

Install the circuit breaker on a compatible DIN rail inside the distribution board, ensuring proper orientation and secure mechanical engagement. Connect the line and load conductors to the appropriate terminals, observing correct tightening torque for secure electrical contact. Verify the breaker rating and characteristic match the protected circuit and coordinate with upstream and downstream protection devices. After installation, switch the breaker on and check for correct operation under normal load conditions.

Usage recommendations

Confirm conductor sizes and terminal torque values per applicable local electrical codes before installation. Coordinate the C20A breaker with upstream protection to maintain selective discrimination where required. Periodically inspect connections and the breaker for signs of wear, overheating, or corrosion, and replace if performance is degraded.
