Product Description
AC IDMT Automatic Overcurrent Protection Relay 5A Single Phase
A relay is intended protect loads or circuits from excessive current.
Description:
Purple Horn 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
