Frequently Asked Questions

What is the difference between a circuit breaker and an MCCB?

A circuit breaker is a general term for a device that protects an electrical circuit from damage caused by overload or short circuit. An MCCB (Molded Case Circuit Breaker) is a type of circuit breaker designed for higher current ratings (typically 10A to 2500A) and is used in industrial and commercial applications where greater protection and adjustability are required.

What will a 2000W pure sine wave inverter run?

A 2000W pure sine wave inverter can power multiple household appliances simultaneously, including laptops, chargers, LED lights, small refrigerators, coffee makers, air fryers, and hair dryers. It provides clean, stable power suitable for sensitive electronics.

Are your products certified for international markets?

Yes, our products are certified with CE, CB, SAA, UKCA, TUV, and other international standards, ensuring compliance with safety and performance regulations in Europe, North America, Australia, and beyond.

Do you offer OEM/ODM services?
