General
The MCM Model JR-2 is a microprocessor controlled, high
current interrupter featuring a high stability, temperature
compensated time base. The JR-2 was specifically designed
for the interruption of multiple rectifier cathodic protection
systems in order to conduct synchronized instant off testing
for extended periods.
Capabilities
The JR-
2’s capabilities include DC interruption in excess of 5
KW loads and AC interruption in excess of l0 KW loads
(Reactive). Also, multiple unit synchronous operation is
guaranteed for a normal five-day workweek. The JR-2 is
sync and program compatible with all other models of the
Model JR family of current interrupters.
