What Class of fuse does the CH363, CH363RB, CH363DS, and CH363AWK safety switches accept?
Canadian HD Switches
Select correct type of fuse
These switches accept Class J fuses as standard. Options include Class R fuses (field install Class R Fuse Kit RFK10) and Class H or K fuses (field relocate the fuse base assembly to alternate position marked in the enclosure when using Class H, K or R fuses). With Class H or K fuses installed, the switches are CSA approved for use on systems with up to 10,000 RMS Symmetrical Amperes available fault current. With Class R fuses (and Class R Fuse Kit RFK10 installed) or Class J fuses installed, the switches are CSA approved for use on systems with up to 200,000 RMS Symmetrical Amperes available fault current.
NOTE: DO NOT USE RENEWABLE LINK FUSES IN SQUARE D SAFETY SWITCHES. The use of renewable link fuses may adversely affect user safety, impair reliability and will void the warranty.
