OOHMAGE OMM6LE Residual Current Operated Circuit Breaker — Remote-ready MCCB with Leakage Protection
The OOHMAGE OMM6LE is a residual-current operated mccb engineered for AC 400 V three-phase systems (4P, 3P+N). It integrates remote control, adjustable leakage protection and cost-control metering to simplify protection design and O&M. With up to Icu/Ics 65/50 kA @ 400 V, the breaker suits feeders and incomers in commercial buildings, industrial plants and energy-aware facilities.
Why choose OMM6LE
- Residual-current leakage protection: Electronic trip module with selectable IΔn stages safeguards personnel and equipment and helps reduce arc-flash risk in mccb distribution.
- Remote control (MD ready): Optional motor operator enables open/close, reset and status feedback for SCADA/BMS; supports external rotary handle for safe local operation.
- Cost control function: Built-in measurement channels support kWh/cost allocation and alarms, cutting add-on meters and wiring.
- Chinese–English shift: Dual-language HMI streamlines commissioning and maintenance across teams.
- Robust short-circuit performance: Up to 65 kA Icu / 50 kA Ics at 400 V allows selective coordination with upstream/downstream mccb 3 phase devices.
- OOHMAGE build: Compact body, low temperature rise and consistent trip curves across the full specification range.

Engineering notes
- Coordination & selectivity: Use upstream/downstream curve staging (Icu/Ics 65/50 kA tier) to maintain service continuity in mccb 3 phase risers; apply ground-fault/residual settings per feeder leakage profile.
- Remote operation safety: Combine MD with door-mounted handle; adopt interlocks to block local closing during remote sequences.
- Thermal performance: Low temperature rise supports denser panels; respect cable cross-section and ventilation to keep conductor ΔT within design limits.
- Commissioning workflow: CN/EN UI reduces setup friction; document setting mccb parameters (IΔn, delays, Inst) in the single-line schedule.
