100% Brand New MTL2220 EARTH LEAKAGE DETECTOR With Best Discount

The MTL2220 continuously monitors floating electrical circuits in a hazardous area, and warns if their resistance to earth falls below 10kΩ. It enables other MTL2000 and 3000 Series units to be used in the ‘no-fail’ mode, whereby earth faults on field lines can be detected and rectified without upsetting control or needing emergency action. The measuring circuit of the unit uses a 1Hz oscillator, amplifier and phase-sensitive demodulator to reject electrical interference up to 250V. A self-test facility enables the unit to be checked automatically or manually from time to time to ensure the integrity of the whole system. Testing is carried out by connecting two safe-area terminals together; this triggers an IS opto-coupler to connect a known resistance across the input terminals, de-energising the relay and LED if the unit is healthy, but having no effect on the monitored circuits. The changeover output contacts are duplicated within the unit for reliability.
