## Summary description

Legrand LE-419170 is a three-phase circuit breaker with a 20A rated current and Type B tripping characteristic. Designed for protection of electrical circuits against overloads and short circuits in three-phase installations, it is suitable for residential and light commercial distribution boards. The device ensures selective disconnection and reliable thermal-magnetic protection where a B characteristic is required.

## Long description

Legrand LE-419170 is a three-phase circuit breaker with a 20A rated current and a Type B trip characteristic. It provides thermal-magnetic protection for three-phase circuits, combining overload and short-circuit detection to protect conductors and connected equipment in residential and light commercial distribution boards. The device is intended for installations that require a B characteristic, offering selective disconnection and coordinated protection for downstream devices.
Advantages
The breaker delivers precise tripping behavior for low fault currents thanks to the Type B curve, which enhances protection for circuits with resistive loads and small inductive components. Compact three-pole construction reduces panel space requirements while maintaining clear phase separation. The thermal-magnetic mechanism ensures dependable performance over repeated fault events and under varying ambient temperatures. Designed by a recognized manufacturer, the unit is compatible with standard DIN-rail distribution enclosures and typical wiring practices.
Suitable for
Protection of three-phase branch circuits in residential distribution boards
Light commercial electrical panels with primarily resistive loads
Circuits supplying heating elements, lighting groups, or small motors with low inrush currents
Key specifications
Poles: three-pole configuration for simultaneous disconnection of all phases
Rated current: 20 A
Tripping characteristic: Type B (suitable for low inrush/resistive-dominant loads)
Protection type: thermal-magnetic (overload and short-circuit protection)
Mounting: DIN-rail compatible enclosure mounting
How to use
Install the circuit breaker in the distribution board on a standard DIN rail according to national wiring regulations and the panel manufacturer’s instructions. Connect line and load conductors to the corresponding terminals, ensuring correct phase sequence and secure torque on terminal screws. Verify that the breaker rating and characteristic match the circuit design, then switch to the ON position to energize the protected circuit. Test the installation after wiring by checking continuity and correct operation of upstream and downstream protective devices.
Usage recommendations
Use this three-phase 20A Type B breaker where selective protection against low-level faults is required and where loads are predominantly resistive or have limited motor inrush. Periodically inspect connections and test protection coordination during routine maintenance to ensure reliable operation.
