Information
Micrologic 7.0H (Harmonics) is an electronic control unit used on Masterpact NT 06 to 16 and Masterpact NW 08 to 63 fixed circuit breakers. This control unit has a selective and earth-leakage protection (LSIV), and is designed to protect power circuits and loads. It embeds adjustable long time protection against overloads. It provides also adjustable short-time protection and instantaneous protection against short-circuits. Micrologic 7.0H offers an adjustable residual earth leakage protection. Micrologic 7.0H indicates overloads with an Alarm LED. It is able to display the trip cause through 3 others LEDs. Micrologic 7.0H is equipped with a digital LCD screen that displays power measurement and current/voltage harmonics. This control unit can be associated with fixed Masterpact NT and NW basic frame.
