The Micrologic 6.0 A (ammeter) is an electronic trip unit used in circuit breakers of the Masterpact NW08 to NW63 type. The trip unit is designed to protect circuits and loads. It features adjustable long-time protection against overload, a short-time delayed protection, and an instantaneous short-circuit protection. Additionally, it offers protection against earth faults. The Micrologic indicates an overload with the help of an alarm LED. Other trip causes are displayed via three additional LEDs. The device is equipped with a digital LCD screen that shows the actual effective values for current with an accuracy of 1.5%. This trip unit can be integrated into a Masterpact NW circuit breaker.
