Frequently Asked Questions (FAQ):
-
Q: What is the primary application of this 40A MCCB?
A: It is primarily used for protecting electrical circuits rated at 40 Amperes. Common applications include serving as a main circuit breaker in distribution panels, protecting motors, feeders, and other equipment in commercial buildings, industrial plants, and infrastructure projects. -
Q: Does the product come with any international certifications?
A: As a manufacturer adhering to comprehensive quality systems, we can provide information on applicable certifications upon request. The specific standards (e.g., IEC, UL) applicable to your market can be discussed based on your order requirements. -
Q: What does the "Mill Test Report" contain?
A: The Mill Test Report is a factory test document that provides verified data on key parameters such as rated current, breaking capacity tests, insulation resistance, and operational checks. It serves as a quality record for the specific batch of products. -
Q: Can the breaking capacity be customized?
A: Yes. We offer standard and high breaking capacity options. You can specify your required short-circuit breaking capacity (Icu) during inquiry to ensure the MCCB matches your system's protection needs. -
Q: Is the 12-month warranty global?
A: The warranty covers manufacturing defects and applies under normal operating conditions as defined in the product documentation. It is valid for our customers worldwide, though specific claim procedures may involve coordination with our support team. -
Q: What are the available mounting types?
A: The MCCB can be supplied as a fixed type for permanent panel mounting or as a plug-in type for easier installation and replacement. Please specify your preference when ordering. -
Q: Are motorized operation options available?
A: Motorized drives for remote operation are an available option. This feature allows the breaker to be integrated into automated or remotely controlled systems. -
Q: How does the thermal-magnetic trip unit work?
A: It employs two protection principles. The thermal part uses a bi-metal element that bends slowly under sustained overload, eventually tripping the mechanism. The magnetic part uses a solenoid that reacts almost instantly to high short-circuit currents, providing fast interruption.
