LA70QS4004 is a specialty fuse developed to protect high-value electrical components, including power supplies and harmonic filters, in industrial and commercial applications. It is released as a new product by Sun Bridge Electric Fuse Co., Ltd to fill the gaps in the existing products.

LA70QS4004 has a fast reaction and strong breaking capacity, suitable for high frequency and high temperature applications, which makes it an optimal solution to protect electrical components from damage due to short circuit and overload. It also provides unique protection for electric shock, by protecting the human body from the damaging power, making it an ideal solution in industrial and commercial applications.

The LA70QS4004 has two types of structures. The full-shell-type structure has an overall protection structure to ensure a compact and secure installation, while the open-type structure provides a lightweight and efficient structure, which is suitable for a variety of applications in limited space.

The working principle of LA70QS4004 is based on the short-circuit protection. In case of a short-circuit or an overload, the current will exceed the safe operable capacity, and the fuse will be triggered automatically, cutting off the power supply. This ensures that the connected electronic components are not damaged by the surge.

In addition, it is designed with multiple protection functions, such as over-current protection, current leakage prevention, back-response prevention and surge protection. It is also equipped with an indelible fuse fuse identification circuit to ensure an accurate identification.

The LA70QS4004 is ideal for applications such as electric motors, rectifier diodes, contactors, power components, high-power power supplies and harmonic filters. This product is DIN 43620 standard compliant and UL 98 approved for use in industrial and commercial applications. It is also RoHS compliant and CE certified, allowing it to be used in a variety of locations.

The LA70QS4004 has a high performance, making it an ideal solution for industrial and commercial electrical components. It provides excellent protection from short-circuits and overloads, making it a cost-effective option for protecting expensive electronic components from damage.
