Schneider Electric 33540 MicroLogic 6.0 E Control Unit for ComPacT NS630b-NS3200 - Withdrawable Electrical
Universal (NS630b-NS3200)A Frame | 3P/4PP | MicroLogic 6.0 E
The Schneider Electric 33540 is a MicroLogic 6.0 E electronic control unit for withdrawable (drawout), electrically operated ComPacT NS circuit breakers. MicroLogic 6.0 offers comprehensive LSIG protection with integrated earth-fault detection using an external sensor for residual current monitoring. The 'E' (Energy) variant provides comprehensive energy metering functions including kWh consumption, power factor, and demand measurements, supporting energy management and billing applications. Compatible with all ComPacT NS frames from NS630b to NS3200 (630A-3200A), this MicroLogic 6.0 E unit uses a rating plug system for precise current adjustment. The control unit snaps directly onto the circuit breaker frame without tools and can be replaced by qualified personnel for field upgrades or maintenance. Protection functions include lsig + earth fault with adjustable pickup levels and time delays. Designed to IEC 60947-2 standards, the 33540 supports the Schneider Electric EcoStruxure power monitoring ecosystem through optional BCM-ULP communication modules. Operating temperature range spans -25°C to +70°C (-40°C for LCD-equipped variants). Green Premium ecolabel certified for environmental compliance. Suitable for main distribution, sub-distribution, motor protection, and generator protection applications across commercial, industrial, and infrastructure installations worldwide. Advanced protection coordination features include zone-selective interlocking (ZSI) capability for enhanced selectivity between upstream and downstream devices, minimizing fault clearance time.
