OMM6RT Dual Adjustable Thermomagnetic MCCB for Protection Coordination
OMM6RT is a thermomagnetic dual adjustable molded case circuit breaker for projects where buyers need more flexible overload and magnetic protection coordination than a standard fixed-setting MCCB. It is suitable for industrial distribution, equipment protection and panel-building applications where current setting and fault-level matching should be confirmed before order.
This series is positioned between standard thermomagnetic MCCB sourcing and more complex electronic MCCB selection. OOHMAGE supports buyers in confirming frame current, adjustment range, pole configuration, breaking capacity, installation needs and document requirements before quotation.
Product Highlights
- Dual adjustable protection: useful when both overload and short-circuit response need closer project matching.
- Thermomagnetic structure: practical for buyers who want adjustability without moving to a fully electronic MCCB.
- Panel-building suitability: helps match equipment panels, feeder circuits and industrial distribution requirements.
- Order confirmation support: OOHMAGE helps organize current, poles, breaking capacity, quantity and packaging details.
Recommended Applications
Choose OMM6RT when the buyer needs adjustable thermomagnetic protection for project coordination. For ordinary standard protection, OMM6 may be sufficient; for electronic settings and broader protection logic, compare OMM6E or OMM6EY.
