SCHNEIDER ELECTRIC MICROLOGIC 6.0 E 47603 MasterPact Electronic Trip Unit, LSIG Protection with Energy Meter

Overview

The SCHNEIDER ELECTRIC Micrologic 6.0 E (47603) is an electronic control trip unit for MasterPact NT, NW and Compact NS air circuit breakers. It provides LSIG four-stage protection plus built-in energy metering function, widely stocked as spare for main power distribution switchgear.

Features This Micrologic 6.0E supports adjustable long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth fault protection. The 47603 variant has LCD display for power parameters, trip recording and fault indication. It can be replaced individually without changing the whole air breaker and supports local parameter setting.

Specs

Model: 47603, Micrologic 6.0 E Series: MasterPact control unit Type: electronic LSIG trip unit with energy metering Protection: L overload, S short-time, I instantaneous, G earth fault Applicable breaker: MasterPact NT, NW, Compact NS Accuracy class: 2% energy measurement Mounting: internal fit inside ACB Protection class: IP20 Certifications: CE, IEC 60947-2 Product status: legacy switchgear spare

Principle

The unit samples three-phase current signals continuously. It executes selective protection logic, records energy consumption data and triggers the breaker mechanism when overload, short-circuit or earth fault occurs. Trip cause and power data are shown on the local LCD screen.

Applications

The Micrologic 6.0 E 47603 is widely deployed in industrial substations, power plants and refinery main switchrooms. It is used for selective protection and power monitoring for MasterPact air circuit breakers.
