OOHMAGE OMM6LE IoT Reclosing Circuit Breaker — Smart MCCB with Remote Reclose & Early-Warning
The OOHMAGE OMM6LE IoT Reclosing Circuit Breaker is a 4-pole (3P+N) smart mccb for AC 400 V systems, engineered for remote control, automatic reclosing, power metering statistics, and rapid fault location. Its electronic release supports coordinated protection on feeders where uptime and granular monitoring matter. Built on a compact platform with robust short-circuit performance (up to Icu/Ics 65/50 kA @ 400 V), it’s well suited to critical distribution panels, commercial buildings, industrial plants, and energy-managed facilities.
Key Advantages
Remote control & auto-reclose: Open/close from SCADA/BMS and enable adaptive reclosing after transient faults to reduce downtime.
Power metering statistics: Onboard measurement for kWh, demand snapshots, and event logs improves load profiling and cost allocation.
Early-warning protection: Threshold alarms (overload trend, temperature rise surrogate via current profile, leakage pre-alarms when paired with upstream RCD) help prevent nuisance trips.
Fast fault location: Time-stamped trip cause and phase identification shorten MTTR in multi-feeder boards.
OOHMAGE build: Low temperature rise, compact envelope, and consistent trip characteristics across the whole current range.

Engineering Notes
Coordination: Use mccb 3 phase selectivity with upstream incomers; set reclose logic only for transient faults (e.g., instantaneous/short delay trips) and lockout on persistent faults.
Thermal margins: Low ΔT frame allows denser busbar spacing; for higher frames, check enclosure ventilation and conductor sizing for continuous load plus harmonics.
Telemetry: Map metering, breaker state, trip cause, and reclose counters to BMS tags for analytics-driven maintenance and energy KPIs.
Commissioning: Document setting mccb parameters (LSI thresholds, reclose attempts, dead time) and store with panel as-built for audits.
Why OOHMAGE
Upgrade feeders with OOHMAGE OMM6LE IoT Reclosing Circuit Breaker to combine mccb protection, remote control, and auto-reclose in one device. Ask for the reclose logic template and BMS point list to speed up commissioning and approvals.
