OOHMAGE OMM6EY Intelligent Measurement “Four-Remote” MCCB
The OOHMAGE OMM6EY Intelligent Measurement Four Remote Circuit Breaker is a smart MCCB for AC 400 V systems that blends metering, telecontrol and high breaking capacity in a compact frame. Designed for modern panels that need fast diagnostics and SCADA readiness, it delivers Icu/Ics up to 70 kA, selective category B, and ≤1 s remote actuation—ideal for plants, data centers, OEM switchboards, and distributed energy projects.
Why spec OMM6EY
- Four Telecontrol Functions (4-Remote): remote measurement, indication, control, and parameter adjustment for fast fault response and SCADA integration.
- Integrated metering: on-board voltage/current/energy measurement reduces extra meters and wiring; supports load profiling and energy audits.
- Dedicated carrier module: reliable comms for long cable runs and noisy electrical environments.
- High breaking capacity: lcu/lcs = 65–70 kA at AC400 V (frame dependent) with ICW up to 10 kA/1 s for selective coordination.
- Stable thermals: small volume with low temperature rise supports dense boards and extended duty.
- Maintenance strategy: maintenance-free option available; with-maintenance life up to 10,000 mechanical cycles.

Application notes
- Industrial feeders & MCCs: coordinate at AC400 V using Ics/Icu values; use ICW for busbar selectivity.
- Smart panels: leverage 4-Remote for load shedding, peak-demand control, and breaker health alarms.
- Digitized facilities: built-in metering supports ESG reporting and energy optimization without external meters.
