AC IDMT Automatic Overcurrent Protection Relay 5A Single Phase

AC IDMT Automatic Overcurrent Protection Relay 5A Single Phase

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..

FEATURES 

A. Low-set inverse definite minimum time relay 
B. High-set instantaneous 
C. Separate low-set and high-set trip indicators 
D. Trip starting indication 

Specifications:

SETTING RANGES 
Low-set: 2A to 6A; 40% to 120%
