Product information

Description

Legrand LE-403357 single-phase 16 A Type B circuit breaker provides compact overcurrent protection for residential and light commercial electrical installations. It features a thermal-magnetic trip mechanism with Type B characteristic, ensuring disconnection on small to moderate short-circuit currents and reliable protection against overloads. The breaker is intended for installation in standard distribution boards where a slender, DIN-rail mounted protective device is required for individual circuits.

Advantages

The device combines thermal overload protection and magnetic short-circuit interruption in a single unit, enabling consistent response to sustained overloads and sudden faults. Its Type B tripping curve makes it suitable for circuits with primarily resistive loads and moderate inrush currents, offering balanced sensitivity and nuisance-trip avoidance. The compact form factor conserves space in the panel and allows for straightforward DIN-rail mounting and wiring. Designed by a recognized manufacturer, the breaker meets typical safety and performance expectations for domestic and light commercial distribution systems.

Suitable for

  • Protection of individual branch circuits in homes and apartments
  • Circuit protection for lighting and socket outlets with predominantly resistive loads
  • Small commercial premises with standard non-heavy motor loads
  • Replacement or upgrade of existing thermal-magnetic protective devices in distribution boards

Key specifications

  • Poles: single-phase (single-pole)
  • Rated current: 16 A
  • Tripping characteristic: Type B (thermal-magnetic)
  • Mounting: DIN-rail compatible, panel installation
  • Operation: manual on/off toggle with trip indication
  • Application: overcurrent protection (overload and short-circuit)

How to use

Install the circuit breaker on a standard DIN rail inside the distribution board following local electrical regulations and manufacturer mounting instructions. Connect the incoming supply conductor to the line terminal and the outgoing circuit conductor to the load terminal, ensuring secure torque on terminal screws and correct polarity where required. After installation, set the breaker to the ON position to energize the protected circuit. If the breaker trips due to overload or short-circuit, identify and rectify the fault before resetting the device to the ON position.

Usage recommendations

Verify compatibility of the breaker’s Type B characteristic and 16 A rating with the connected loads and inrush currents. Use this breaker for circuits with limited motor starts or inductive spikes; for heavy motor loads or circuits with high inrush currents consider devices with different tripping characteristics. Ensure periodic inspection of connections and the distribution board environment to maintain reliable operation.
