Company Profile

Q1: Are you a trading company or a manufacturer?
A: We are Integration of industry and trade, our company has a history of 40 years. We have been specializing in the production of a series of photovoltaic electrical products, such as circuit breaker, pv combiner boxes, pv connector, surge protector, pv fuses, pv tool accessories and etc.  

Q2: If OEM is acceptable?

A: We can provide OEM and ODM services. We have many different specifications and appearances for customers to choose.

Q3: Do you provide sample? Free or charge?

A: We can provide free samples to customers, but only one piece, but customers need to bear the freight. For some special products, we also offer free samples. Considering their particularity, we usually refund the sample fees to customers after they place formal orders.  

Q4: How long is your delivery time?

A: Our delivery time is determined according to the purchase quantity. Generally, it is about 3-40 days, less than 300 pieces within 5 days, 300-2000 pieces within 7-15 days, 2000-20000 only within 15-40 days.  

Q5: What circuit faults are protected against?

A: Protect overload, short circuit, some models can protect undervoltage failure. When the current exceeds the rated value, the circuit will be automatically cut off for a long time; Short circuit when the current instantaneous maximum will be disconnected; Under voltage (if supported) also operates when the voltage is below the normal range.

Q6: How is overload protection implemented?

A: Internal thermal trip device. When the overload current heats up the heating element, according to Joule's law, the heat reaches a certain degree, and the bimetal plate bends and deforms due to the difference in thermal expansion coefficient to trigger the circuit breaker action.

Q7: What are the specifications of rated current and rated voltage?

A: Rated current from a few amps to several hundred amps, such as 6A for small power circuits, 200A for large equipment, etc. The rated voltage is 220V (home and small business), 380V (three-phase power and industrial), etc., depending on the load and power supply voltage.
