This MicroLogic 6.2 E-M (Energy) is a 3 poles 3d electronic trip unit used on ComPacT NSX 100/160/250 circuit breakers. This 80A rating electronic trip unit is an optimum choice for motor protection applications. It embeds an adjustable long time protection against overloads. It provides also an adjustable short-time protection and a fixed instantaneous protection against short-circuits. It offers a phase unbalance or phase loss protection, and an additional and adjustable ground fault protection. MicroLogic 6.2 E-M indicates overloads with Alarm LEDs. The green Ready LED flashes if the circuit breaker is ready to trip. MicroLogic 6.2 E-M is equipped with a display module that gives energy measurement and allows fine adjustment settings. This product is part of our EcoStruxure Power architecture if associated with PowerTag NSX and ComPacT NSX basic frame.
