<p>The HTB-28I-R Fuseholder is one of the more reliable and popular products in the fuseholders range. It utilizes patented technology to provide over-current protection to installations where traditional fuses may not be reliable. The fuseholder is composed of a fiberglass body that houses two contact terminals, each with its own dedicated electrical connection. <p>The HTB-28I-R is designed for use in the most demanding applications, such as powering HVAC, electrical appliances, and machine tools. The fuseholder uses a metal shield to protect against electromagnetic interference. This EMI protection is achieved by the use of an encapsulated PC Board, which is molded directly onto the fiberglass body. This eliminates the need for any additional expensive shielding and gives the HTB-28I-R a superior performance when compared to other fuseholders. <p>The HTB-28I-R’s working principle revolves around two components: a metal case and a PC Board. The metal case houses two power contact terminals, which are connected to the main line by shielded cables. These terminals connect to a printed circuit board, or PC Board, which is located in the center of the body. The PC Board is then connected to an external power source. The external power source is regulated via a set of self-switching relays that are controlled by the input voltage.</p><p>The self-switching relays ensure that the fuseholder only draws the amount of power required by the application. The relays use a sensitive electronic circuit to monitor the input voltage and will automatically shut off the main power supply if the current exceeds the predetermined level. This ensures that the fuseholder and the circuit are protected from dangerous surges in voltage which can be caused by an overload or a short circuit.</p><p>The HTB-28I-R is the perfect solution for applications where safety or reliability of the circuit is paramount. It is designed to be used in areas with a high risk of electrical interference such as industrial sites or manufacturing facilities. The HTB-28I-R is also popular for its easy installation process, as all of the components can be connected together with minimal effort. Because of its supreme performance and reliability, the HTB-28I-R has become the preferred choice for many electrical engineers.</p>
