Test power adapter A 1722 PRCD adapter

safetysingle-phase/three-phase

The A 1722 PRCD Adapter is a multi-function test adapter intended for safety and functional testing of different types of 1-phase and 3-phase PRCDs. KEY FEATURES • Simulation of errors on input mains • Accessible Inputs/Outputs for easy connection of safety testers • Enables testing Continuity in PRCDs with the PE wire monitored • Functional testing of the following types of PRCD’s: PRCD-S (1-phase / 3 pole and 3-phase / 5pole) PRCD-S+ (1-phase / 3 pole) PRCD-K/Di (1-phase) PRCD (2pole and 3pole) • Functional testing, simulation of following faults: 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 • Measurement of protective conductor • Measurement of insulation resistance • Measurement of PE-current with optional current clamps • Tripping test • Probe test
