Two RCD testers that comply with EN61557 for testing, measuring or monitoring of protective measures.
Tests 30mA, 100mA, 300mA and 500mA rated RCDs
1/2x I, I, 5x I tests standard, DC and selective RCDs
0° or 180° polarity tests on all RCDs
Selective breakers have a time delay in tripping. When selected, trip test times are extended and a 30s delay is allowed between the measurement of the fault voltage and the application of the test current
Selectable touch voltage inhibit and touch voltage display on the analogue bargraph
300Vac (25 to 45Hz) voltage measurement range
Clear 20mm high digit LCD display with analogue arc bargraph
Tough rubber armoured case with self-contained display cover that locks away underneath the instrument during use
Safety input terminal interlock - prevents unsafe connection of test leads
Safety lock-out prevents the test from operating when the circuit voltage is >300V
