Frequently Asked Questions (FAQ)

Q1: What is the main function of an MCCB?
A Moulded Case Circuit Breaker (MCCB) is designed to protect electrical circuits from excess current, which typically causes overloads or short circuits. It acts as an automatic switch that shuts off power to prevent system damage.
Q2: What breaking capacity options are available for this series?
We offer multiple breaking capacity ratings classified by type letters, including B (20kA), C (35kA), S (50kA), H (65kA), G (85kA), and X (100kA) to fit various industrial safety environments.
Q3: Can the MCCB be operated in demanding atmospheric conditions?
Yes, it operates reliably within temperatures of -5°C to +40°C and features strong resistance to salt spray and oil mist. It is designed to function well up to altitudes of 2000m, provided the environment is free from explosive hazards and conductive dust.
Q4: Do you offer OEM custom manufacturing services?
Yes, we provide extensive OEM/ODM manufacturing customization. We can supply the products either under neutral packaging, custom specifications, or help you establish your position as a local market distributor.
Q5: What details should I provide when placing an order?
To process your order efficiently, please supply the product name, exact model and frame level, breaking capacity, poles (e.g., 3P or 4P), rated current, protection type, and your final order quantity.
Q6: Which safety approvals and quality standards do these breakers comply with?
Our manufacturing follows strict ISO9001 guidelines, and the products are fully compliant with major international standards and certifications, including CE, RoHS, CB, SEMKO, TUV, and KEMA.
