NEW product: A 1722 PRCD adapter

We have launched another new accessory: A 1722 PRCD adapter, designed for functional and electrical safety testing of single and three-phase portable residual current devices (PRCDs). It supports simulation of different error states and has connection inputs for testing of PE wire (if monitored by PRCD). Among supported tests is also the probe test (to test PRCD's touch electrode) in addition to other standard tests for PRCD testing.
Supported functional testing of the following PRCD types:
  • PRCD-S (1-phase / 3-pole and 3-phase / 5-pole)
  • PRCD-S+ (1-phase / 3-pole)
  • PRCD-K/Di (1-phase)
  • PRCD (2-pole and 3-pole)
Supported fault simulations (for functional testing):
  • L-open (for 3-phase L1-L3)
  • N-open
  • PE-open
  • Reversed wires (for 1-phase L <> PE / L <> N, for 3-phase L1,L2,L3 <> PE / L1,L2,L3 <> N)
  • External voltage on PE
Other supported tests and measurements include:
  • Measurement of protective conductor
  • Measurement of insulation resistance
  • Measurement of PE-current with optional current clamps
  • Tripping test
  • Probe test
The A 1722 PRCD adapter is supported by the following instruments:
  • MI 3155 EurotestXD
  • MI 3152 EurotestXC
  • MI 3152H EurotestXC 2.5kV
