The Micrologic 2.0 A (ammeter) is an electronic trip unit used with Masterpact NW circuit breakers. The trip unit is designed to protect circuits and loads. It has adjustable long-term protection against overload and instantaneous short-circuit protection. 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.
