Description
Product Introduction
Facing an unexpected trip or mechanism failure on your main distribution panel? The EATON MDS6163HEA-NNNNN-LCC2E-NNNAX handles high-current switching and protection across heavy industrial power systems. Built to conform with ANSI C37 and IEC 60947 standards, it slots directly into standard Magnum DS switchgear cells without requiring cell frame modifications.
In field deployments of Eaton Magnum DS switchgear, this breaker unit maintains clear fault isolation within cycles of overcurrent events. The EATON MDS6163HEA-NNNNN-LCC2E-NNNAX connects directly into main power bus bars to keep facility power systems running smoothly. Listed prices serve as a baseline market reference; actual costs depend on current global surplus availability.

Installation & Configuration Guide
Phase 1 — Pre-Installation (est. 10 min)
De-energize and lock out the switchgear cell power supply. Wait 5 minutes for internal discharge paths to clear residual voltage. Gather a torque wrench, racking handle, digital multimeter, and an ESD grounding wrist strap. Export or log current trip unit parameters using your electronic setup tool. Take clear photos of all secondary disconnect wiring, terminal blocks, and option switches on the active EATON MDS6163HEA-NNNNN-LCC2E-NNNAX unit.
Phase 2 — Removal (est. 5 min)
Label every secondary wiring connection before unplugging auxiliary harnesses. Insert the racking handle into the drawout mechanism and crank counterclockwise to move the breaker from CONNECTED to DISCONNECTED position. Carefully pull the unit out onto the cell extension rails. Lift the module off the rails using a rated lifting yoke, taking care not to strike primary stabs. Inspect cell stabs for arcing marks or debris.
Phase 3 — Installation (est. 10 min)
Put on your static wrist strap and bond it to cabinet ground. Unpack the replacement EATON MDS6163HEA-NNNNN-LCC2E-NNNAX from its shipping enclosure. Verify the catalog number on the side nameplate. Match all trip unit rotary switch settings to the photos taken in Phase 1. Lower the unit onto the drawout extension rails, aligning secondary disconnect blocks. Push the breaker into the TEST position and crank clockwise until the mechanism locks into the CONNECTED position. Torque terminal hardware to ~10 N·m where applicable.
Phase 4 — Power-On & Testing (est. 15 min)
Verify auxiliary power voltage using your multimeter before closing control circuits. Apply auxiliary control voltage. Check front panel status flags: mechanical indicator should show DISCHARGED / OPEN. Connect your secondary injection test kit, run a primary trip test across all three phases, and verify pickup times. Perform a manual racking test, cycle the breaker open and closed via control switches, and confirm stable operation for 30 minutes under idle cell power. Record the serial number swap in your site maintenance database.
