Custom microprocessor controlled for highest accuracy and reliability. 3 LEDs for checking correct wiring status. 15mA LOOP measurement: LOOP impedance 2000Ω range measurement is carried out with low test current (15mA). The current will not cause tripping out involved RCD even the one with the lowest nominal differential current (30mA). Direct reading of Prospective Short Circuit Current (PSC). Safe voltage measurement function. Large custom digital display readout on all models. Measure low loop resistances(resolution of 0.01Ω). Automatic lock-out if test resister overheats. Large custom digital display readout . Visual indication of reversed phase and neutral wiring at socket. Designed to IP54 Rating. Complies with IEC 61557

The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands. The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set.
