Effective December 2015 Supersedes April 2014 Technical Data 2021 BUSSMANN SERIES KAZ and MIS 13⁄32˝ x 2˝ 600Vac KAZ actuator and MIS non time-delay pin indicating supplemental fuses Catalog symbol / color code: • KAZ •  • Black (600Vac max actuator - not a fuse) 0.25 Min. (Blown Position) (6.35) 0.063 Max. (Unblown Position) (1.60) Black (600Vac max 1 to 12A) Description: Features: KAZ is a non-fuse actuator (not a fuse) for use in parallel with a 50 amp or greater fuse to provide indication a fuse has opened by opening at 10 or more amps. The KAZ can also be applied in a 1-, 2- or 3-pole block with miniature signaling switches to provide remote status indication. KAZ (not a fuse) MIS fuses are non time-delay pin indicating supplemental fuses used to provide a visual indication of an open fuse condition.
