Frequently Asked Questions (FAQ)
-
Q: What is the primary function of the FKM2DC Circuit Breaker?
A: Its primary function is to provide reliable overload and short-circuit protection specifically for electric motors, isolating them from the power supply in case of a fault to prevent damage. -
Q: Can this breaker be used as a main circuit isolator for a motor?
A: Yes, the FKM2DC is suitable for use as both a protective device and a manual isolator/disconnector for motor circuits, provided its rated operational voltage and current match the application. -
Q: How do I select the correct rated current (In) for my motor?
A: The breaker's rated current should be selected based on the motor's full-load current (FLC) as stated on its nameplate, typically choosing a value slightly higher to accommodate normal starting inrush currents without nuisance tripping. -
Q: Are auxiliary contacts available for remote signaling?
A: Yes, auxiliary contact modules are available as optional accessories. They can be easily mounted on the side of the breaker to provide signals for remote monitoring of the breaker's status (ON/OFF/Tripped). -
Q: Is the FKM2DC suitable for use in DC motor circuits?
A: The "DC" in the model name refers to the frame size designation. For specific application in DC circuits, please consult our technical team, as voltage and breaking capacity ratings differ for DC. -
Q: What is the typical delivery lead time for an order?
A: Lead times vary based on order quantity and specific configuration. Standard configurations often have shorter lead times. We recommend contacting our sales team for an accurate delivery estimate. -
Q: Do you provide technical support for panel design integration?
A: Absolutely. Our technical team can provide guidance on integrating the FKM2DC into your control panel designs, including recommendations for coordination with other protective devices like contactors and overload relays. -
Q: Are your products certified for use in my country/region?
A: The FKM2DC is designed to comply with international standards (IEC/EN). For specific national certifications required in your target market, please inquire with our sales department for detailed compliance information.
