Frequently Asked Questions (FAQ)

Q: What are the typical applications for this DC miniature circuit breaker?
A: It is ideally suited for DC power distribution and protection in applications such as photovoltaic (PV) solar systems, telecommunications power supplies, battery energy storage systems, electric vehicle charging infrastructure, marine and RV electrical systems, and industrial DC control circuits.
Q: How does the 6kA breaking capacity benefit my system?
A: A higher breaking capacity means the breaker can safely interrupt a larger short-circuit current. This is crucial for systems with powerful DC sources (like large battery banks or solar arrays) to prevent catastrophic failure, fire hazards, and ensure the safety of the entire installation.
Q: What is the lead time for customized orders?
A: Lead times vary based on the complexity and quantity of the customization. Standard configurations are typically available from stock. For custom ratings, curves, or branding, please contact our sales team with your specifications for an accurate timeline.
Q: Is this breaker suitable for both indoor and outdoor use?
A: The breaker itself is designed for indoor installation within appropriate enclosures or distribution boards. For outdoor applications, it must be housed in a suitably rated and sealed enclosure that protects it from direct moisture, UV exposure, and extreme temperatures.
Q: Can I get samples before placing a bulk order?
A: Yes, sample units are available for qualified buyers for evaluation purposes. Please reach out to us to discuss sample availability and terms.
Q: What standards does this product comply with?
A> Our FK6-63DC breaker is designed and tested in accordance with IEC/EN 60898-2 and GB/T 10963.2 standards for circuit-breakers for overcurrent protection for household and similar installations in DC applications.
Q: Do you provide technical support or datasheets?
A: Absolutely. We provide comprehensive technical datasheets, CAD drawings, and application notes. Our engineering team is also available to offer support for integrating our breakers into your specific system design.
Q: What is your minimum order quantity (MOQ) for customized items?
A> The MOQ for customized specifications depends on the specific requirements. We strive to be flexible to accommodate both prototype projects and large-scale production runs. Please consult with us for detailed MOQ information.
