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.
  • Smooth direct currents
For installations up to 40 or 63 A and sensitivities of 30 or 300 mA.
INStantaneous tripping curve.

Applications

All electrical installations where process continuity is critical and the protection of persons (30 mA) and machines (300 mA) is required, with non-adjustable immediate activation.
Such as, for example:

  • Computer systems (UPS)
  • Speed drives
  • Photovoltaic installations
  • Electric vehicle charging systems
