Circuit breaker Legrand 419202 LS C16A 1P 6kA 1-module

Legrand 419202 LS C16A 1P 6kA 1-module is a single-pole miniature circuit breaker with a C tripping characteristic and a nominal current rating of 16 A. Designed for modular distribution boards, it provides reliable overcurrent protection by interrupting overloads and short circuits with a breaking capacity of 6 kA. The device fits a single module on DIN-rail systems and is suitable for protecting lighting circuits, socket circuits and small appliances in residential and light-commercial installations.

Advantages

This circuit breaker offers standardized single-module sizing for compact panel layout and straightforward replacement. The C-characteristic provides balanced sensitivity to both resistive and inductive loads, making it suitable for general-purpose circuits. Its 6 kA breaking capacity ensures clear interruption of short-circuit currents up to that level, supporting safety in typical low-voltage installations. The unit is compatible with modular DIN-rail mounting and integrates with common accessories and busbar systems.

Suitable for

• Protection of household lighting circuits
• Protection of socket outlets and small appliances
• Distribution boards in apartments and small commercial spaces
• General-purpose circuits with mixed resistive and inductive loads

Key specifications

• Poles: single-pole (1P)
• Tripping characteristic: C curve
• Rated current: 16 A
• Short-circuit breaking capacity: 6 kA
• Module width: 1 module (1M)
• Mounting: DIN-rail modular distribution boards
• Intended system: low-voltage AC circuits

How to use

Install the circuit breaker into the modular DIN-rail distribution board according to applicable wiring regulations and the distribution board manufacturer instructions. Ensure the supply is de-energized before making connections. Connect the phase conductor to the breaker line terminal and the load conductor to the load terminal, observing correct tightening torque values. After wiring, switch on the supply and verify correct operation by switching the breaker on and off. For any changes to protective settings or replacement, consult a qualified electrician.

Usage recommendations

Use this breaker in circuits where a 16 A rating and C-characteristic are appropriate; avoid using it where higher fault-current interruption or different tripping curves are required. Verify coordination with residual-current devices and downstream protective devices when designing the distribution board. Periodically inspect for signs of wear, overheating, or loose connections and replace the device if damaged.
