Circuit Breaker Legrand LE-419235 three-phase 16A Type C

Legrand LE-419235 three-phase 16A Type C circuit breaker provides overcurrent protection for three-phase electrical installations. It is designed to detect and interrupt overloads and short circuits while fitting standard DIN-rail distribution panels. The device uses a C-type trip curve suitable for moderate inrush currents and offers a compact form factor for installation in residential, commercial, and light industrial switchboards.

Advantages

The circuit breaker combines selective C-type tripping with a rated current of 16A to balance motor inrush tolerance and sensitive protection of conductors and equipment. Its modular design allows straightforward mounting on standard DIN rails and integration with common distribution accessories. The device provides reliable thermal-magnetic protection, rapid disconnection in fault conditions, and consistent mechanical durability for repeated switching operations.

Suitable for

• Protection of three-phase branch circuits in residential and commercial buildings
• Feeding and protecting small motors and pumps with moderate starting currents
• General-purpose distribution for lighting, sockets, and HVAC subcircuits

Key specifications

• Number of poles: three-phase (3-pole)
• Rated current: 16 A
• Tripping characteristic: Type C (thermal-magnetic)
• Function: overload and short-circuit protection
• Mounting: DIN-rail compatible modular housing
• Operating environment: indoor electrical distribution panels
• Switching capability: suitable for frequent switching and reliable fault interruption

How to use

Install the breaker on a standard DIN rail inside an appropriate distribution enclosure, ensuring power is isolated before work. Connect the three incoming phase conductors to the breaker line terminals and the load conductors to the load terminals, respecting phase order and torque recommendations from the panel manufacturer. Verify correct wire sizing for a 16 A rated device and secure protective covers and barrier separators according to local electrical codes. After installation, energize the circuit and test proper operation by simulating load conditions and confirming the breaker remains closed under normal load and trips under fault conditions.

Usage recommendations

Use this three-phase 16A Type C breaker where moderate inrush currents are expected, such as small motors or grouped lighting circuits. Ensure coordination with upstream and downstream protective devices to maintain selectivity. Regular visual inspection and periodic testing under controlled conditions are recommended to confirm reliable operation and compliance with local electrical standards.
