Heavy Duty Safety Switch

Resolution:
Provisions for installing Class J fuses are included in 30 - 400 A, 600 V and 100 - 400 A, 240V, fusible heavy duty safety switches. Conversion to Class J fuse spacing requires relocating the load side fuse base assembly (or assemblies where applicable) from the standard Class H or R fuse location to an alternate position as marked in the switch enclosure. Switches rated 600 A, 240V or 600V, require the addition of an adapter kit, catalog number H600J.
