Circuit breaker Legrand LE-419204 single-phase 25 A Type C

Legrand LE-419204 single-phase 25 A Type C miniature circuit breaker provides overcurrent and short-circuit protection for residential and light-commercial electrical installations. Designed for DIN-rail mounting, this single-pole device interrupts fault currents while allowing normal operation of connected loads. The Type C tripping characteristic makes it suitable where moderate inrush currents occur, combining reliable protection with compatibility for lighting circuits, socket outlets and small appliances.

Advantages

The circuit breaker features a compact housing that saves panel space and simplifies installation on standard DIN rails. Type C tripping ensures a balanced response to overloads and short circuits, reducing unwanted nuisance trips from devices with moderate start-up currents. Its single-phase design is optimized for protecting individual lighting and power circuits while providing clear mechanical ON/OFF indication for ease of maintenance.

Suitable for

• Protection of residential lighting circuits
• Protection of socket outlet circuits in homes and small offices
• Protection of small motors and appliances with moderate inrush current
• DIN-rail distribution boards in apartments and light-commercial premises

Key specifications

• Poles: single-pole (single-phase)
• Rated current: 25 A
• Tripping characteristic: Type C (moderate inrush tolerance)
• Mounting: DIN-rail compatible
• Application: overload and short-circuit protection for lighting and socket circuits

How to use

Install the circuit breaker on a standard DIN rail inside the distribution board and connect the phase conductor to the breaker terminal and the neutral conductor to the common neutral bus. Ensure power is isolated before wiring. After installation, switch the breaker to the ON position to restore the circuit. In the event of an overload or short circuit the breaker will trip to the OFF position; identify and correct the fault before resetting the breaker. Follow local electrical codes and, if necessary, consult a qualified electrician for installation and verification.

Usage recommendations

Use this Type C, 25 A breaker for branch circuits that supply lighting, general-purpose sockets and equipment with moderate starting currents. Do not use it where a different tripping curve or higher interrupting capacity is required; select protective devices according to the complete system fault level and equipment specifications.
