Product information

Description

Legrand residual current circuit breaker 2P P312 combines residual current detection with overcurrent protection in a compact two-pole device. It is rated for 16 A with a B characteristic for short-circuit/overload response and a residual tripping sensitivity of 0.03 A (30 mA). Type AC operation detects sinusoidal alternating current leakage to earth and the unit is designed for DIN-rail mounting in residential and light-commercial distribution boards.

Advantages

The device provides combined earth-leakage and overcurrent protection in a single module, reducing the number of separate components required in a distribution board. Its 30 mA sensitivity supports personal protection against electric shock, while the B characteristic ensures timely disconnection for common overload and short-circuit conditions. Compact form factor and DIN-rail compatibility simplify installation and integration into standard electrical panels.

Suitable for

  • Residential main and sub-distribution boards
  • Light-commercial electrical installations
  • Protection of circuits feeding sockets, lighting, and small appliances
  • Retrofit projects where space and combined protection are required

Key specifications

  • Poles: 2P (two-pole)
  • Rated current: 16 A
  • Tripping curve: B characteristic
  • Residual operating current: 0.03 A (30 mA)
  • Residual current type: AC (sinusoidal AC leakage detection)
  • Mounting: DIN-rail
  • Application: combined residual current and overcurrent protection

How to use

Install the breaker on a standard DIN rail inside the distribution board following applicable electrical regulations and local codes. Connect phase and neutral conductors to the input and output terminals according to the wiring diagram and ensure all connections are tightened to the manufacturer’s recommended torque. Verify correct polarity and that the device rating (16 A, B curve, 30 mA residual) matches the protected circuit. After installation, perform appropriate insulation and earth-leakage tests and check correct tripping operation before placing circuits into regular service.

Usage recommendations

Use this device where combined protection against earth leakage and overcurrent is required, and pair it with correctly rated upstream and downstream protective devices. For circuits with electronic loads or where pulsating residual currents are expected, confirm compatibility with type AC residual detection or choose a device with a different residual type if necessary. Periodically test the trip function and follow local maintenance schedules.
