Class H, R, J, and L Fuse Provisions:
Class R Fuse
Class H or K Fuse Provisions: Fusible Square D 30–600 A heavy duty safety switches accept Class H or K fuses as
standard. With Class H or K fuses installed, the switch is UL Listed for use on systems with up to 10 kA available fault
current.
Class R Fuse Provisions: Fusible Square D 30–600 A heavy duty safety switches will accept Class R fuses as
standard. A field-installed rejection kit is available which, when installed, rejects all but Class R fuses. With the installation
of the rejection kit and Class R fuses, the switch is UL Listed for use on systems with up to 200 kA available fault current.
See Class R Fuse Kits, page 3-16.
Class J Fuse Provisions: Provisions for installing Class J fuses are included in 30–400 A 600 Volt, and 100–400 A 240
Volt, fusible heavy duty safety switches. Conversion to Class J fuse spacing requires relocating the load side fuse base
assembly from the standard Class H fuse location to an alternate position as marked in the enclosure. With Class J fuses
installed, the switch is UL Listed for use on systems with up to 200 kA available fault current. Switches rated 600 A, 240
or 600 Volt, require the addition of an adapter kit, H600J. One kit per three-pole switch.
Class L Fuse Provisions: Fusible 800 A and 1200 A safety switches use Class L bolt-in fuses and are rated for use on
systems with up to 200 kA at 600 Vac maximum. 1200 A switches accept class L fuses from 601–1200 A, 800 A switches
accept class L fuses from 601–800 A.
