The KLKD series fast-acting 600 V ac/dc fuses are used in solar combiner boxes and in circuits with dc fault currents up to 50,000 A. These fuses are designed to meet both the UL and IEC photovoltaic fuse specifications and are available in standard and board-mount configurations. The KLKD midget fuses also have high-interrupting and current-limiting capability. They are intended to supplement the primary branch-circuit fuse or breaker to provide backup overcurrent protection. The KLKD fuses are non-indicating and may be used with an indicating fuse block or cover. These fuses are offered in a wide range of ampere ratings to match specific requirements in a variety of applications. Note that 1–5 A meets UL 1741 GFDI requirements.
