## Summary description

Legrand 419170 is a three-pole (3P) miniature circuit breaker with B20A tripping characteristic and 6 kA breaking capacity. Designed for overcurrent and short-circuit protection in electrical installations, it occupies 3 modules (3M) on a DIN rail. Suitable for residential and light commercial distribution boards where selective B-characteristic protection is required.

## Long description

Legrand 419170 B20A 3P 6 kA 3M is a three-pole miniature circuit breaker designed to protect electrical circuits against overloads and short circuits. With a B20A tripping characteristic and a rated breaking capacity of 6 kA, this device provides reliable interruption of fault currents in distribution boards. The breaker occupies three standard DIN-rail modules and is intended for installation in residential and light commercial electrical panels where selective B-characteristic protection is required.
Advantages
The three-pole configuration allows simultaneous disconnection of all phases for enhanced safety and system integrity. The B20A curve offers sensitive protection for circuits supplying general-purpose sockets and lighting, reducing nuisance trips for typical resistive and moderately inductive loads. Compact 3-module width ensures efficient use of panel space while maintaining accessible terminals and straightforward DIN-rail mounting. The 6 kA breaking capacity meets common requirements for domestic and small commercial installations, providing a balance between performance and compactness.
Suitable for
Overcurrent and short-circuit protection in three-phase residential electrical panels
Protection of distribution circuits feeding sockets, lighting, and small motors
Small commercial installations and service rooms with moderate fault-current levels
Key specifications
Poles: 3-pole (three-phase) configuration
Tripping characteristic: B-curve, nominal current 20 A
Breaking capacity: 6 kA rated short-circuit interruption capability
Width: 3 standard DIN-rail modules
Mounting: DIN-rail compatible housing for easy panel installation
Application: Overcurrent protection for circuits feeding sockets, lighting and small motors
How to use
Install the circuit breaker on a standard DIN rail inside the distribution board following local electrical codes and installation practices. Ensure correct orientation and firm mechanical engagement on the rail, then connect phase and load conductors to the input and output terminals, tightening terminals to the manufacturer’s recommended torque. Verify the nominal 20 A setting fits the protected circuit and that upstream and downstream protective devices are coordinated. After wiring, switch the breaker on and perform functional checks to confirm correct operation and absence of wiring faults before energising circuits.
Usage recommendations
Use this B20A three-pole breaker where selective protection for general-purpose circuits is required. Coordinate with upstream protection to ensure discrimination and verify that fault-current levels in the installation do not exceed the breaker's 6 kA capacity. Periodically inspect terminals for tightness and signs of overheating, and test switching operation after significant load changes or maintenance.
