The PCS20-H is a 20-ampere, double-hole mount semiconductor protection fuse designed for direct mounting on printed circuit boards with extremely fast-acting, current-limiting characteristics. It is rated for 600VAC and 600VDC operation with an interrupting rating of 200kA AC and 100kA DC, providing robust protection for semiconductors, circuit breakers, and critical components. The fuse features a melting I²t of 41 A²s and a clearing I²t of 330 A²s at 600VAC, with a response time of =10ms, ensuring rapid fault isolation. With a power loss of 2.6W at 80% rating and 4.4W at 100% rating, the PCS20-H enables automated assembly by eliminating the need for clips and fuse blocks while delivering superior I²t protection and higher voltage ratings directly at the board level. This UL Component Recognized fuse is ideal for applications requiring reliable semiconductor protection and reduced board complexity.
