Information
This MicroLogic 7.3 E AL (Energy) is a 3 poles 3d electronic trip unit used on ComPacT NSX 400/630 circuit breakers. This 400A rating electronic trip unit is an optimum choice for all standard and specific applications. It embeds adjustable long time protection against overloads. It provides also adjustable short-time protection and instantaneous protection against short-circuits. MicroLogic 7.3 E AL provides an earth leakage alarm without trip, that is available on the terminal block. MicroLogic 7.3 E AL indicates overloads with Alarm LEDs. The green Ready LED flashes if the circuit breaker is ready to trip. MicroLogic 7.3 E AL 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.
