Other instruments / adapters / accessories

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. The adapter supports simulation of different error states and it has connection inputs for testing of PE wire (if monitored by PRCD), probe test (to test PRCD's touch electrode) and other applicable tests for standardized PRCD’s testing. If used together with the MI 3155 Eurotest XD AUTO SEQUENCE®, the complete PRCD can be tested (state-by-state) electrically and functionally with a push of a button. It is possible to create a professional PRCD-based report with MESM.
