NOTE: Schneider Electric DOES NOT Manufacture or Sell Fuses for General Duty Heavy Duty or Double Throw Safety Switches.

The 100amp General Duty Safety Switches accept Class H or K fuses as standard. For design Series F01 or F03, options include Class R fuses (field install Class R Fuse Kit RFK10). With Class H or K fuses installed, the switch is UL/CSA listed for use on systems with up to 10,000 RMS Symmetrical Amperes available fault current. With Class R fuses (and RFK10 fuse kit installed) the switch is UL/CSA listed for use on systems with up to 100,000 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.
