Schneider Electric 9999-SF4 Double Fuse Holder

Schneider Electric's 9999-SF4 is a two-fuse control-circuit fuse holder kit designed for Type S NEMA contactors and motor starters (NEMA sizes 00–7). The kit provides two fuse locations for CC-class fuses, rated up to 6 A at 600 VAC, and is UL Listed and CSA certified for North American use. Fuses are not included, and the holder is designed to accept standard 600 V Bussmann Type KTK fuses. This field-installable SF4 assembly mounts with Type S contactors to protect the control circuit, making it suitable for motor-control panels and other applications that require dual control-circuit protection. The SF4 is part of Schneider Electric’s Class 9999 fuse-holder family for NEMA contactors.
