RCDT310-EN-BS, Megger

RCDT310 & RCDT320 RCD Testers 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 RCDT320 model additional features 10mA/1A RCD extended test capability Backlit display and range selection ideal for low light environments Ramp Test measures & displays the actual trip current of an RCD. Ideal for diagnosing nuisance tripping of RCDs Auto testing allows remote testing from the RCD under test. The RCDT320 will automatically perform a 1//2 I, I and 5I test at both 0°and 180°. When the RCD trips the user resets it and the tester proceeds to the next test automatically. All results are displayed at the end of the test 25 to 450Hz Frequency measurement range Optional 2-wire test leads supplied 3-phase safe - Meets the requirements of BSEN 61010-1 for safe connection to a 440V Installation Category III supply (300V phase to Earth) Weatherproof to IP54 Dimensions (WxHxD): 190 x 75 x 140mm; Weight 980g Note RS is an authorised Megger distributor.
