OOHMAGE OMM6EY Intelligent Four-Remote Circuit Breaker — Compact Smart MCCB with Fast Telecontrol
The OOHMAGE OMM6EY Intelligent Four-Remote Circuit Breaker is a compact smart mccb for AC 400 V distribution that integrates the classic “four-remote” functions—remote monitoring, metering, control, and alarm—into a rugged thermomagnetic platform. A new, space-saving design with complete specifications and built-in measurement makes it ideal for feeders that demand fast response (≤1 s), clear event visibility, and reliable breaking performance up to Icu 85 kA.
Key Advantages
Small volume, big capability: High interrupt ratings in a compact frame simplify panel layout and heat management.
Four-remote functionality: Remote open/close, status & trip cause, real-time metering, and alarms for early intervention.
Complete specifications: Wide current bands (125–800 A classes) cover mains, feeders, and critical loads.
Measurement function: Integrated kW/kWh and current/voltage monitoring support energy KPIs and cost allocation.
OOHMAGE build quality: Low temperature rise, consistent trip curves, and clean wiring with 3P/4P options.

Engineering Notes
Selectivity/coordination: For multi-tier boards, coordinate mccb settings (L/S/I) with upstream incomers to maintain service continuity.
Telemetry mapping: Expose breaker state, trip cause, currents/voltages, power/energy, and alarm flags to BMS/SCADA via four-remote interface.
Commissioning checklist: Record setting mccb parameters and meter CT/PT scaling (if used) for audit and maintenance.
