| OEM flexibility | Important for private label programs and distributors building a branded low-voltage range. |
| Documentation clarity | Clear documentation keeps technical approval, quotation alignment, and engineering communication consistent. |
| Responsive communication | Fast communication keeps specification confirmation, sample confirmation, and order alignment moving. |
⎯⎯ Product Scope
MCCB Product Scope
VIOX supplies molded case circuit breakers for low-voltage protection across feeders, panels, machinery, and sub-distribution duties, with different trip-unit directions, pole configurations, and accessory options by series.
Trip Direction
Thermal-magnetic or electronic by series
System Fit
Feeder, panel, machinery, and low-voltage distribution use
Accessory Review
Shunt trip, auxiliary, undervoltage, and handle direction by model
Supply Models
Catalog supply, OEM development, and private label cooperation
| Series item | Configuration scope |
|---|---|
| Trip-unit direction | Whether the series uses thermal-magnetic or electronic logic and whether that matches the application. |
| Current and frame suitability | Which frame and current direction best fits the target panel, feeder, or equipment load. |
| Pole configuration | The pole structure required for the target market and installation. |
| Icu and Ics direction | Whether the interrupting capability suits the installation fault duty and project expectations. |
| Accessory compatibility | Which auxiliaries, shunt trips, undervoltage releases, or external operators are available for the exact family. |
| Standards and approvals | Which standards or certifications apply to the quoted MCCB series and target market. |
Important: Exact ratings, approvals, trip settings, and accessory combinations depend on the selected MCCB series and model.

Accessory Direction
Auxiliary, shunt trip, undervoltage, or handle options by model
| Variant direction | Application direction | Configuration focus |
|---|---|---|
| Thermal-magnetic MCCB | General low-voltage distribution, feeders, and conventional protection duties where simplicity and proven protection behavior matter. | Current rating, breaking capacity, trip curve behavior, and whether fixed or adjustable settings are needed. |
| Electronic trip MCCB | Projects that need more precise adjustment, improved coordination, or more advanced protection tuning. | Protection functions, setting range, accessory or communication requirements, and coordination goals. |
| Pole and frame selection | Applications where the breaker must match single-phase or three-phase system structure and panel layout. | Pole count, frame suitability, installation space, and downstream system requirements. |
| Accessory-ready series | Projects that require auxiliary signaling, remote trip, undervoltage functionality, or external operation hardware. | Accessory compatibility, mounting method, and documentation matched to the exact MCCB family. |
Important: Exact current ranges, interrupting ratings, certifications, and accessory combinations depend on the selected MCCB series and model.
⎯⎯ Selection Guide
MCCB Selection Factors
VIOX supplies molded case circuit breakers for low-voltage protection across feeders, panels, machinery, and sub-distribution duties, with different trip-unit directions, pole configurations, and accessory options by series.
1.Confirm the product family
Start with application type, current direction, fault-duty expectations, pole count, and trip-unit preference.
2.Align branding and packaging
Clarify logo, package format, labeling direction, and any supporting documentation needed for the brand program.
3. Confirm samples and technical details
Quoted series, accessory fit, and documentation stay aligned before volume orders.
4. Repeat-order supply
Series continuity and commercial alignment stay consistent across future orders.
⎯⎯ Quality Control
Quality Control Focus
Quality control centers on product-family consistency, series-specific documentation, mechanical and electrical checks, and clear handling of samples and repeat orders.
Series-specific control
Model-level clarity keeps quoted breaker families aligned with the actual supply scope.
Accessory and configuration accuracy
For MCCBs, compatibility around auxiliaries, operating mechanisms, and release options matters as much as the base breaker.
Documentation discipline
Clear quotations, datasheets, and specification details reduce mistakes during technical approval and repeat orders.
Repeat-order continuity
Repeat-order continuity keeps the same family aligned across future quotations and supply cycles.
⎯⎯ Buyer Fit
Export Supply Fit
Export-oriented MCCB supply combines product availability with technical fit, commercial handling, private label direction, and accessory matching for the target market.
| Evaluation point | Factory supply focus |
|---|---|
| Product consistency | Repeatable structure and stable supply across multiple orders. |
| Technical communication | Clear model logic, usable quotations, and understandable series documentation. |
| Accessory completeness | Confidence that the required release, contact, and handle directions can be matched correctly. |
| Certification alignment | Series matched to the target market rather than relying on generic page-level claims. |
| OEM capability | Support for branding, labeling, packaging, and branded-range development where needed. |
| Long-term cooperation | Confidence that repeat orders can be handled with consistent commercial and technical logic. |
