A load disconnect switch, which is suitable for AC 50Hz with a rated voltage up to AC690V and a rated thermal current up to 3150A, is a combination of a fuse and an isolating switch. The disconnect switch disconnects the normal operating current, while the fuse interrupts the circuit fault current, thus cutting off the load current. At the same time, the load isolating switch is equipped with an arc extinguishing device to handle overload current. But be careful, it is used for infrequent circuit connection and disconnection, as well as for electrical isolation.This product complies with standards GB/T14048.3 and IEC60947-3.

Our Advantage
Selected Materials: Key conductive components (such as contacts) are made of high-quality, high-conductivity copper, while the housing is constructed from flame-retardant, impact-resistant, and aging-resistant advanced engineering plastics (such as PC and PA66) or high-quality electroplated steel, ensuring product safety and longevity from the ground up.
Precision Craftsmanship: High-precision molds and automated production lines ensure component consistency. Advanced welding, riveting, and assembly processes guarantee high mechanical strength, low contact resistance, and stable connections.
Strict Quality Inspection: Full quality inspection is performed from incoming raw materials to shipping finished products. 100% testing for electrical, voltage, and mechanical operation ensures that every switch shipped meets or exceeds national (GB) and international (IEC) standards.
Flexible Customization: OEM/ODM services are available based on specific customer requirements (such as rated current, voltage, number of poles, wiring configuration, mounting dimensions, color, and brand logo). We respond quickly to tailor-make the most suitable product for you.
FAQ
Q: What is the expected lifespan/operating cycle of this product?
A: 1500 times
Q: What should I do if a disconnector is mistakenly pulled or closed while under load during operation?
A: A mistaken disconnector generates an arc as soon as the contacts separate. Closing the disconnector immediately can extinguish the arc and prevent an accident. However, if all contacts are already open, reclosing the mistakenly pulled contact is not permitted. For single-pole disconnects, if one phase is operated and the other two phases are mistakenly pulled, continue operation.
Q: Can I get detailed technical drawings/datasheets/CAD files for this product?
A: Of course, pls leave your message on our web. or contact us by email. We'll reply to you ASAP.
Q: How many is your MOQ ?
A: One piece. We'd like to ship one piece to your for testing first. Then purchase in bulk if there is no problem.
