Electrical, Specialty Fuses

Fuses have long been a trusted protective device used to protect electric circuits from overloads and short circuits. The 70CJ fuse, made of ceramic-bodied joules, is a more modern fusing technology designed for applications requiring higher current ratings than levels provided by the traditional time delay fuse. This type of fuse is ideal for protecting low-voltage circuits from high-current overloads and short circuits.The 70CJ fuse offers increased performance, making it a popular option for many different applications. The key features of the 70CJ fuse include high current rating, current limitation, fast response time, and low power consumption. The 70CJ fuse has a nominal rating of up to 70 amperes and has a maximum interrupting rating of 40,000 amperes. It is a single-pole device with a dual-pole filament, preventing current ratings from short circuiting. In addition, the 70CJ fuse has a response time of under 4 milliseconds.The 70CJ fuse operates on the principle of a temperature-dependent current limitation fuse. The ceramic-bodied fuse has two components: a resistance wire and a heat-generating element. The heat-generating element is a semiconductor-type resistor that creates a small amount of heat when current passes through it. This, in turn, heats up the resistance wire, which begins to increase in resistance as the temperature rises. This increase in resistance causes a reduction in current, limiting current flow and protecting the circuit.The 70CJ fuse also contains overload protection features. If the current exceeds the fuse’s rating, the temperature-dependent current limitation element will reduce the current, providing a safeguard against overloads. In addition, the dual-pole filament within the fuse prevents current from flowing more than 40,000 amperes.The 70CJ fuse is suitable for use in a variety of applications. It is often used in motor control centers, homes, office buildings, and other areas that require a high level of current protection. Due to its high current rating, the 70CJ fuse is ideal for protecting circuits that include high-powered appliances such as electric heaters, fans, etc. Additionally, this type of fuse is often used in photovoltaic panels on residential and commercial properties.Overall, the 70CJ fuse is an important protective device with a variety of applications. It offers high performance, long life, and a fast response time. The temperature-dependent current limitation element provides effective overload protection, while the dual-pole filament prevents current from short circuiting. This makes the 70CJ an ideal protective device for a range of current applications.
