Product Details
Class H Fuse Provisions:
• Fusible Square D 30 through 600 ampere heavy duty safety switches accept Class H fuses as standard. With Class H fuses installed the switch is UL listed for use on systems with up to 10,000 RMS symmetrical amperes available fault current.
Class R Fuse Provisions:
• Fusible square D 30 through 600 ampere heavy duty safety switches will accept Class R fuses as standard. A field installable rejection kit is available which, when installed, rejects all but Class R fuses, the switch is UL listed for use on systems with up 200,000 RMS symmetrical amperes available fault current.
Class J Fuse Provisions:
• Provisions for installing Class J fuses are included in 30 through 400 ampere 600 Volt, and 100 through 400 ampere 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 200,000 RMS symmetrical amperes available fault current.
• 3 Wire (3 Blades and Fuseholders) - 600 Vac, 600 Vdc.
• On 3-Pole devices, use two outside poles for switching DC.
• 400 and 600 Amp - 600 Vac only
