Frequently Asked Questions (FAQ)

What does "50kA Icu" mean for this circuit breaker?
"Icu" stands for Rated Ultimate Breaking Capacity. A 50kA rating means the breaker is tested and certified to safely interrupt a short-circuit current of up to 50,000 Amperes, which is a measure of its maximum fault-clearing capability.
What customization options are available for the FKW1 MCCB?
We offer customization on several fronts: specific rated current values (within the FKW1 frame limits), choice between thermal-magnetic or electronic trip units, selection of poles (3 or 4), and the addition of various accessories like auxiliary switches, alarm switches, shunt trips, and undervoltage releases.
Is this MCCB suitable for both 50Hz and 60Hz power systems?
Yes, the FKW1 Molded Case Circuit Breaker is designed to operate effectively on both 50Hz and 60Hz alternating current systems, making it suitable for a wide range of international applications.
Can this breaker be used for motor protection?
Absolutely. When configured with the appropriate thermal-magnetic or electronic trip unit settings, the FKW1 MCCB can provide reliable overload and short-circuit protection for electric motors.
What are the main differences between fixed and plug-in mounting versions?
Fixed breakers are permanently wired into the panel. Plug-in versions have a base that is wired permanently, and the breaker itself can be "plugged" in and out. This allows for easier replacement or maintenance without rewiring the entire panel.
What standards does this product comply with?
The FKW1 MCCB is designed and manufactured in compliance with the international standard IEC 60947-2 for low-voltage circuit breakers. Other specific certifications can be discussed based on project requirements.
What is the typical delivery time for a customized order?
Delivery time depends on the complexity of the customization and order quantity. Standard configurations may have shorter lead times. We recommend contacting our sales team with your specific needs for an accurate timeline.
How do I select the correct rated current for my application?
The rated current should be selected based on the full load current of the circuit it is protecting, with consideration for ambient temperature and installation conditions. Our technical team can assist you in selecting the optimal rating during the quotation process.
