Code: P16121.

  • Usefull diam.(mm): 35
  • Delay: INS
  • Sensitivity: 300 mA

INFORMATION

Description

Residual current protection device for the protection of people and property against fault currents, such as:

  • Sinusoidal alternating currents and pulsating residual direct currents..
  • Sinusoidal alternating currents, up to 1 kHz.
  • Direct currents

For installations up to 125 A and sensitivities of 30 or 300 mA. INStantaneous/SELective activation of the circuit breaker, circuit breaker with fast trigger coil or contactor.

Applications

All electrical installations where process continuity is critical and protection of persons (30 mA) and machines (300 mA) is required, with non-adjustable immediate or SELective activation.

  • Computer systems (UPS systems)
  • Speed drives
  • Photovoltaic installations
  • Electric Vehicle Charging systems
