Description

Brief Product Description

The Schneider Electric MICROLOGIC 6.0A is a high-precision electronic trip unit featuring an integrated ammeter for Masterpact NT and NW circuit breakers. It delivers comprehensive LSIG protection—Long-time, Short-time, Instantaneous, and Ground-fault—to ensure maximum safety in complex electrical distribution networks.

​Product Description

Comprehensive LSIG Protection and Monitoring

The MICROLOGIC 6.0A serves as the intelligence center for Masterpact NT and NW air circuit breakers. This control unit utilizes advanced microprocessor technology to provide full LSIG protection, which safeguards industrial power systems against overloads, short-circuits, and critical ground faults. Beyond simple tripping functions, the “A” designation signifies an integrated ammeter that provides real-time current measurements on a built-in digital display. Consequently, facility managers can monitor phase loads directly at the breaker, facilitating better load balancing and preventive maintenance strategies.

Enhanced System Selectivity and Reliability

To minimize operational downtime, the Schneider MICROLOGIC 6.0A incorporates adjustable settings that enable precise selective coordination. This capability ensures that only the circuit breaker closest to a detected fault trips, leaving the remainder of the electrical network energized. The unit also features high-performance ground-fault protection, which is essential for protecting equipment against insulation failures and reducing fire risks in 3-pole and 4-pole configurations. By maintaining stable performance across a broad voltage range up to 690V AC, this module provides a steadfast defense for high-capacity infrastructure.

Rugged Industrial Design for Extreme Conditions

Engineered for the most demanding environments, the MICROLOGIC 6.0A operates reliably in ambient temperatures ranging from -25°C to +70°C. Its compact architecture is designed to resist electromagnetic interference and withstand humid conditions up to 95% non-condensing. Because the unit maintains an internal memory for fault trip history and operational data, technicians can quickly diagnose the root cause of electrical events. This combination of rugged hardware and intelligent data logging makes the Micrologic series a critical component for modern, smart power distribution systems.
