Circuit Breaker Legrand LE-419200 Single-Phase 10 A Type C

Legrand LE-419200 Single-Phase 10 A Type C miniature circuit breaker provides overcurrent and short-circuit protection for single-phase electrical circuits. Designed for DIN-rail mounting, this device combines a 10 A rated current with a Type C tripping characteristic to deliver selective response to inrush currents while interrupting overloads and faults. It is intended for residential and light commercial installations where reliable protection and compatibility with standard distribution boards are required.

Advantages

The Type C characteristic allows the breaker to tolerate moderate transient currents from motors and fluorescent lighting without nuisance tripping, while still providing effective protection against sustained overloads and short circuits. Compact DIN-rail design ensures straightforward installation in standard enclosures and simplifies replacement or expansion of distribution circuits. The device is manufactured to recognized standards for miniature circuit breakers, offering consistent operation and clear mechanical indication of the tripped state.

Suitable for

• Protection of lighting and socket circuits in apartments and houses
• Protection of small motors and pumps with moderate inrush currents
• Distribution boards in small commercial or office premises
• Replacement or upgrade of existing 10 A single-phase circuit breakers

Key specifications

• Rated current: 10 A
• Tripping characteristic: Type C (moderate inrush tolerance)
• Poles: single-phase (1P)
• Mounting: DIN-rail compatible
• Function: thermal-magnetic overcurrent and short-circuit protection

How to use

Install the breaker on a standard DIN-rail in the distribution board, ensuring the supply and load conductors are correctly connected to the input and output terminals and tightened to the manufacturer's torque values. Verify the nominal voltage and the circuit design before energizing. Use appropriate protective measures: isolate the supply, confirm zero voltage on conductors, and follow local electrical codes and safety practices during installation and maintenance. After installation, test the circuit by switching the breaker on and verifying correct operation under normal load conditions.

Usage recommendations

Choose this 10 A Type C breaker when your circuit includes small motors, LED or fluorescent lighting, or equipment with moderate inrush currents that require selective tripping. For circuits with sensitive electronics or very high inrush devices, evaluate whether a different tripping characteristic or additional protective elements are more suitable. Periodically inspect connections and perform functional checks in accordance with local regulations.
