Frequently Asked Questions (FAQ):

Q: What is the primary application for this 4-pole 40A MCCB?
A: It is primarily used in industrial three-phase AC power distribution systems (e.g., 380V/400V/415V) where protection for all three phases and the neutral conductor is required, such as in main distribution boards, panelboards, and for protecting large motors or capacitor banks.
Q: Can this breaker be used as a main incoming switch?
A: Yes, it is suitable for use as a main circuit breaker or a feeder breaker in industrial distribution panels, provided its breaking capacity is appropriately rated for the available fault current at the installation point.
Q: What is the difference between thermal-magnetic and electronic trip units?
A: A thermal-magnetic unit provides fixed protection curves for overload (thermal) and short-circuit (magnetic). An electronic trip unit offers adjustable settings, advanced protection functions (like ground fault), and communication capabilities for system monitoring, providing greater flexibility and precision.
Q: Is this breaker suitable for DC applications?
A: This product is primarily designed for AC power systems. For DC applications, specific DC-rated circuit breakers are recommended. Please consult with our technical team for your specific DC voltage and current requirements.
Q: What are the standard mounting dimensions or footprint?
A: Mounting dimensions vary depending on the specific model and design. Detailed dimensional drawings are available upon request to ensure proper panel layout and compatibility.
Q: Do you offer auxiliary contacts or shunt trips as accessories?
A: Yes, a range of accessories such as auxiliary contacts (for signaling), undervoltage releases, and shunt trips (for remote opening) are typically available to customize the breaker's functionality for your control scheme.
Q: What is the lead time for an order of these breakers?
A: Lead times depend on the order quantity and specific configuration (standard vs. customized). We maintain efficient production schedules and can provide estimated delivery timelines upon receipt of your inquiry.
Q: How do I select the correct breaking capacity for my application?
A: The required breaking capacity (Icu) must be equal to or greater than the prospective short-circuit current at the point of installation. Our technical support team can assist you in selecting the appropriate model based on your system data.
