OMB1-63 6kA Miniature Circuit Breaker for Standard Distribution Boards
OMB1-63 is a compact 6kA miniature circuit breaker for standard low-voltage distribution boards, lighting circuits and general circuit protection projects. It is positioned for buyers who need a practical MCB model with stable supply, familiar DIN-rail installation and clear current / pole / curve confirmation before quotation.
For distributors and project buyers, OMB1-63 works well as a regular stock or project-use MCB when the requirement is standard overload and short-circuit protection rather than a specialized high-fault-capacity application. OOHMAGE supports model selection, packaging communication, technical document discussion and one-year warranty support according to agreed order terms.
Why Choose OMB1-63
- Standard 6kA positioning: suitable for common residential, commercial and light industrial distribution applications.
- Compact modular design: practical for DIN-rail distribution boards and space-conscious panel layouts.
- Multiple current options: helps buyers organize mixed orders for different final circuits.
- Project-friendly sourcing: suitable for distributors, panel builders and electrical project suppliers.
Recommended Applications
Choose OMB1-63 when the project needs a reliable 6kA MCB for standard AC low-voltage circuits. If the order requires stronger short-circuit capacity or a higher-spec project model, compare OMB3-63 or OMB4-63 before confirming the final series.
