OOHMAGE OMM7E New Energy Electronic MCCB
The OOHMAGE OMM7E New Energy Electronic Molded Case Circuit Breaker is built for high-voltage AC distribution up to 1,140 V where compact size, fast setup, and reliable selectivity matter. An electronic long-time/short-time unit paired with a magnetic instantaneous release delivers precise, repeatable protection, while modular internal accessories simplify on-site configuration for mccb 3 phase switchboards in renewables, mining, rail auxiliaries, and heavy industry.

Key advantages
Convenient & fast commissioning: Electronic release with clear dials (0.4–1.0 In) shortens setup vs. purely thermomagnetic units; ideal where frequent setting mccb adjustments are required.
Green & efficient: Low temperature rise design reduces enclosure heat load and improves system efficiency under continuous duty.
High-voltage coverage: Certified operation across AC380/415 / 690 / 800 / 1,000 / 1,140 V—one platform for multi-voltage plants.
Modular accessories: Shunt/UVT/aux contacts and motor operator options support interlocks, remote indication, and automated schemes.
Compact footprint: Short arc-distance (50–100 mm, frame-dependent) enables denser panels without sacrificing breaking performance.

Application guidance
Renewables & ESS: 690–1,000 V feeders, battery racks, step-up transformer secondaries.
Industrial & mining: 690–800 V motors, conveyors, crushers—where high mccb interrupt ratings and tight panels are typical.
Transport & marine auxiliaries: 1,000–1,140 V auxiliary systems needing remote operation and quick re-settings.
Procurement guidance (for buyers comparing harga mccb)
Select the OOHMAGE OMM7E frame by Icu/Ics at your actual operating voltage and ambient. The H-level curve keeps Ics=Icu up to 1,000–1,140 V, cutting oversizing and panel space. Electronic settings (0.4–1.0 In) help coordinate with upstream MV breakers and downstream drives, reducing nuisance trips and lifecycle cost.
