Fuseholders are used to house fuses and protect circuits from being overloaded. They come in a variety of shapes and sizes, depending on their application. The two most common types are panel-mounted and embedded fuseholders. Panel-mounted fuseholders are typically surface-mounted to a panel or printed circuit board assembly (PCBA) for easy access and replacement of fuses while embedded fuseholders are installed directly into the printed circuit board (PCB) and can be more difficult to access and replace.

2193 application field and working principle is a popular type of fuseholder. It is a surface-mounted, panel-mounted fuseholder. It is designed to be used with 2103, 2110, and 2113 series fuses, as well as UL Class RK5 fuses. The fused terminal block can be easily mounted onto a panel with mount holes pre-drilled for mounting hardware. The contact components are made of phosphor bronze with nickel-plated contacts, and a stainless-steel cover plate provides additional protection to the contacts. The housing is made of UL-approved nylon. The contact design is compliant with both UL and IEC standards for 20A applications.

The 2193 application field and working principle is designed for reliable, cost-effective protection of electrical circuits. It can be used to protect the full load of an electronic circuit board or as an overcurrent protection device on transformer and appliance lines. It can also be used to protect motors and other high-powered circuits from overcurrent or short circuits. The fuseholder should be installed in an appropriate location and be easily accessible so that the fuse can be quickly replaced to restore electrical power if a malfunction of the system occurs.

The working principle of the 2193 is simple. When the current drawn from the circuit passes through the fuse holder, the heat generated causes the contact bridge to expand, causing contact with the fuse. If the current draw exceeds the rated current, the contact bridge expands further and breaks contact with the fuse, thus opening the circuit. The contact bridge is designed such that it automatically closes the circuit again when the temperature of the fuseholder returns to a safe level.

The 2193 application field and working principle offers reliable performance and cost-effective protection for electrical circuits. It is highly recommended for use in areas where electrical safety is a priority. With its rugged construction and UL listing, it ensures the safety of the circuit over long periods of time. The fuseholder is also UL and IEC compliant, making it an attractive choice for many applications.
