The Micrologic 6.0 E (energy measurement) is an electronic trip unit that is used with Masterpact NW08 to NW63 circuit breakers. The trip unit is designed to protect circuits and loads. It has adjustable long-term protection against overload, short-time delayed and instantaneous short-circuit protection. It also offers protection against earth faults. The Micrologic indicates an overload using an alarm LED. Other tripping causes are indicated by 3 additional LEDs. The device is equipped with a digital LCD screen that displays the actual RMS values for the current with an accuracy of 1.5%. This trip unit can be integrated into a Masterpact NW basic switch.
