Circuit Breaker Legrand LE-419136 single-phase 16A Type B

Legrand LE-419136 single-phase 16A Type B circuit breaker is designed for overload and short-circuit protection in single-phase electrical installations. It provides thermal-magnetic trip characteristics with a Type B curve, suitable for circuits with low to moderate inrush currents. Built for DIN-rail mounting, this device is intended for use in residential and light commercial distribution boards to safeguard lighting circuits, socket outlets and small appliances.

Advantages

This circuit breaker offers coordinated protection with a Type B tripping characteristic that responds quickly to short-circuits while tolerating normal startup currents. Compact DIN-rail design allows straightforward installation and integration into standard consumer units. The device is rated 16A, providing a clear and consistent current limit for typical household and small-business circuits. Its thermal-magnetic mechanism combines reliable overload detection with rapid magnetic response to fault conditions.

Suitable for

• Lighting circuits in residential and commercial premises
• Socket outlet protection for small appliances
• Individual circuit protection in DIN-rail distribution panels
• Circuits with low to moderate inrush currents (motors under small load, LED drivers)

Key specifications

• Poles: single-phase (single-pole) configuration
• Rated current: 16 A
• Tripping characteristic: Type B thermal-magnetic curve
• Function: overload and short-circuit protection
• Mounting: DIN-rail compatible
• Short-circuit response: rapid magnetic trip for fault currents

How to use

Install the circuit breaker on a standard DIN rail inside the distribution board, ensuring that supply and load conductors are connected to the correct terminals and that the device is mounted in accordance with local electrical regulations. Verify the breaker rating matches the protected circuit wiring and connected load. After installation, test operation by switching the breaker on and off; routine inspection and testing should be performed according to applicable safety standards and maintenance schedules.

Usage recommendations

Use this 16A Type B breaker for general lighting and socket circuits where motor inrush and transient currents are limited. Avoid applying it to circuits with high startup currents or large inductive loads unless coordinated protection studies indicate suitability.
