The Metravi 1813 is a ELCB/RCCB Tester.

The main function of the tester is to test and measure the trip values of ELCB/RCCB in trip time (expressed in ms) or -in trip current value (expressed in mA).

This enables 10mA / 30mA / 100mA / 300mA / 500mA and 1000mA differential circuit breakers to be tested irrespective of their type (normal or delayed). This comprehensive appliance can also be used to test the conformity of the network and the connection of the earthing conductor.
