## Summary description

Single‑phase circuit breaker Legrand LE-419137 rated 20 A, characteristic Type B. Designed to provide overcurrent protection in residential and light commercial electrical installations. Protects circuits against overloads and short circuits, suitable for branch circuits and individual appliance protection. Compact DIN-rail compatible design for standard distribution boards.

## Long description

Legrand LE-419137 single-phase circuit breaker rated 20 A with Type B tripping characteristic provides overcurrent protection for residential and light commercial electrical circuits. The device is designed for mounting on standard 35 mm DIN rails and fits common distribution boards, offering compact protection for branch circuits and individual appliances. This single-pole breaker interrupts fault currents to reduce the risk of wiring damage from overloads and short circuits while maintaining compatibility with typical household and light commercial installations.
Advantages
The circuit breaker offers a compact form factor that suits standard distribution panels and helps save space in electrical cabinets. Its Type B characteristic delivers predictable magnetic tripping at low fault currents, making it appropriate for protecting general-purpose lighting and socket circuits. The device provides reliable thermal-magnetic protection, combining overload sensitivity with fast response to short-circuit events. Construction and terminal design facilitate secure conductor connection and safe operation under rated conditions.
Suitable for
Protection of lighting circuits in dwellings and apartments
Protection of socket outlets and small appliances
Branch circuit protection in small commercial premises
Retrofit installations in standard DIN-rail distribution boxes
Key specifications
Poles: single-pole (single-phase)
Rated current: 20 A
Tripping curve: Type B (magnetic trip at low multiple of In)
Mounting: 35 mm DIN-rail compatible
Protection type: thermal-magnetic overcurrent protection (overload and short-circuit)
Typical applications: branch circuits, lighting, socket circuits
How to use
Install the breaker into a compatible distribution board by snapping it onto a 35 mm DIN rail and secure incoming and outgoing conductors to the designated terminals, observing correct polarity and tightening torque recommended by local wiring standards. Ensure the panel is de-energized before installation. Use the breaker as the overcurrent protective device for a single-phase branch circuit; switch to the OFF position before performing maintenance on the protected circuit. Verify continuity and proper operation by testing the breaker after installation and after any maintenance work.
Usage recommendations
Match the breaker rating and Type B characteristic to the specific circuit load and connected equipment. For circuits with high inrush currents (motors, compressors), consider a device with a different tripping curve. Follow local electrical codes for conductor sizing, torque values, and protective coordination; consult a qualified electrician for design or modifications to the electrical distribution.
