Automatic Inverse Time Protective Relays IDMT Overcurrent Protection

 

 

Time overcurrent relays operate with a time delay, which is adjustable. For given setting, the actual time delay depends on the current through the relay coil. Higher current will cause a faster operation of the relay. The minimum relay operation current (pick-up current) is also adjustable.

The most commonly used overcurrent relay has both the instantaneous response for very large currents and the inverse time response for lower currents. A relay  is intended protect loads or circuits from excessive current.

 

 

Description:

 

KRIPAL overcurrent protection delivers comprehensive protection schemes for low voltage applications. All Mikro's overcurrent units are microprocessor-based numerical relays and are housed in high-strength protective casing. The models in the range provide a wealth of options including programmable relay outputs to static, and digital display or dial activated..
