          FEATURES

          3RV MPCB /contactor combination for fuseless motor feeder (type -2 coordinated ). Rotary operating mechanism . MPCB with "Relay function ". A totally new cocept . Suitable for service temperatures upto 70°C Current limiting type. Tripping time < 5 msec Wide range of site fittable accessories , common for complete range . Trip free mechanism . SHORT -CIRCUIT PROTECTION 3RV MPCs have a standard short -circuitbreaking capacity of 50 kA or 100 kA a voltage of 415 V AC. They are practically short -circuit -proof at this voltage as higher short -circuit -proof currents arenot usually encounted at the installation point .

          ADVANTAGES

          Short circuit proof for faults upto 50 KA high system uptime. Visual On/Off/Trip indication ,reset function ,padlock feature. "Relay function "-results in longer life of the system because the contactor interrupts overload faults ,instead of the MPCB. Reliability of protection is ensured . Faster fault clearing for enhanced life of installations. Flexibility in designing the system with minimum inventory. Positive opening in the event of faults.
