Fuses

Fuses are an important part of an electrical system, and the protective device of last resort. They ensure that the electrical system has protection from accidental overloads that could cause damage or destroy expensive equipment and possibly cause fires or other disasters. The BK1/S505-8-R is one such fuse, used in a variety of applications.The BK1/S505-8-R is a small, non-interrupting, Class CC time-delay fuse with a cylindrical shape. It has a 10A breaking capacity with a 800VAC voltage rating. The lower breaking limit is 6A. It features an UL listed LPN thermoplastic enclosure and is rated for 1 to 3 pole circuit breakers. The fuse also features a thermal time delay feature that requires a minimum interruption time of 13 milliseconds, while allowing overloads up to 10 times the rated current for up to five seconds without blowing.The BK1/S505-8-R is designed for use in various appliance, motor, and lighting applications, including washing machines, air conditioners, electric fans, incubators, microwave ovens, hair dryers, toasters, coffeemakers, and lighting circuits. The thermal time delay feature helps to protect the electrical components from damage due to a sudden surge or overload.The BK1/S505-8-R is also used in motor protection applications, such as those found in elevators and escalators. Elevators and escalators rely heavily on motors, which can be subject to overloads and short circuits. The BK1/S505-8-R helps to protect these motors by having a thermal time delay, preventing premature fuse blowing, even during overloads.The BK1/S505-8-R has a working principle that is similar to that of standard fuses. When the current flowing through the fuse exceeds the rated current, the internal element of the fuse starts to heat up due to the resistance of the material. This causes the element to expand, and when it reaches its maximum size the element will rupture, causing an interruption in the circuit. The thermal time delay feature of the BK1/S505-8-R however, allows the fuse to continue to conduct the current for a certain amount of time before it ruptures, which allows it to handle overloads more effectively than standard fuses.The BK1/S505-8-R is a versatile and dependable fuse, and is an ideal choice for a number of applications. Its thermal time delay feature makes it especially helpful for motors, as it is able to protect them against short circuits and overloads. The 10A breaking capacity and 800VAC voltage rating also make it suitable for a variety of electrical components and circuits, helping to keep them safe and reliable.
