Frequently Asked Questions (FAQ)
Q1: What is the main application of this FK6-63 circuit breaker?
A1: This MCB is primarily designed for residential distribution board installations. It protects final sub-circuits in homes, such as those powering lighting, sockets, and common household appliances, from overcurrent and short-circuit faults.
Q2: What does the "63" in FK6-63 signify?
A2: The "63" indicates the rated current of the breaker, which is 63 Amperes. This is the maximum continuous current the breaker is designed to carry without tripping under normal conditions.
Q3: Is this breaker suitable for three-phase power systems?
A3: Yes, it is suitable. The FK6-63 is available in multiple pole configurations, including 3P and 4P versions, which are designed for use in three-phase residential or light commercial distribution systems.
Q4: What is the difference between Type C and other tripping characteristics?
A4: Type C MCBs have a magnetic trip setting that is higher than Type B. They are ideal for circuits with moderate inrush currents, such as those feeding small motors, transformers, or multiple lighting points commonly found in residential settings, providing protection without nuisance tripping.
Q5: Can this MCB be used as a main switch for isolation?
A5: While it has a manual ON/OFF switch, a miniature circuit breaker is primarily a protective device. For safe isolation and maintenance, a dedicated isolator switch is recommended in accordance with local electrical regulations.
Q6: What wire sizes are compatible with the terminals?
A6: The screw-type terminals are designed to accommodate standard copper conductors. The specific compatible wire size range (e.g., 1.5mm² to 16mm²) should be verified against the product's detailed datasheet, as it can vary.
Q7: Does the product come with any international certifications?
A7: The breaker is designed to comply with international standards such as IEC/EN 60898-1. Specific certification marks on the product can be confirmed upon request, as they may vary based on the target market.
Q8: What is the typical lead time for an order?
A8: Lead times depend on the order quantity and specific configuration required. As a manufacturer, we maintain production flexibility. Standard configurations often have shorter lead times, which can be confirmed during the quotation process.
