12 Product Description The Square D brand Heavy Duty Safety Switch is designed to be tough, reliable and provide exceptional performance in the most grueling conditions; from commercial and institutional to industrial and manufacturing facilities. Square D F Series safety switches provide significantly higher levels of mechanical endurance than NEMA KS-1 requires. The design life of a Square D F-Series switch is a minimum of three times the NEMA requirement. An abundance of copper is used in the heaviest current carrying power paths of all Square D Heavy Duty Safety Switches. The more copper for current carrying paths, the lower the temperature rise. Managing temperatures inside the switch is the key to providing greater service life. All heavy duty safety switches feature a quick-make, quick-break operating mechanism, a dual cover interlock and a color-coded indicator handle. Series F Operating Mechanism Series F Visible Blades Configuration Two or three fusible switched poles with or without insulated, solid grounded neutral Four or six fusible switched poles without insulated, solid grounded neutral Two, three, four or six non-fusible, switched poles without insulated, solid grounded neutral Three fusible switched poles without insulated solid grounded neutral interlocked to Appleton, Crouse-Hinds, or Hubbellock receptacle Three non-fusible switched poles without insulated solid grounded neutral interlocked to Appleton, Crouse-Hinds, or Hubbellock receptacle Construction Visible blades for positive blade position indication Optional viewing window allows visual verification of blade position without opening door; not available on NEMA Type 4X fiberglass reinforced polyester or Krydon enclosures or NEMA Type 7 or 9 enclosures Red and black handle indication for switch position Series F handle, mechanism, and lock plate are field replaceable Series F Type R devices have side-opening covers Highly visible embossed ON-OFF marking Quick-make, quick-break, spring-driven operating mechanism Front removable mechanical lugs.

Factory-installed fuse pullers on A NEMA Types 4, 4X, and stainless steel, NEMA Type 4X fiberglass reinforced polyester, Krydon and NEMA Types 1 or 1K switches. Available for field installation on A F Series switches, NEMA Types 1 and R switches. Class J fuse provisions on A 0 A, 0 V switches and 0 A, V switches. 0 A devices require a mounting kit (catalog number H0J). 0 A switches are shipped with standard Class H fuse spacing. These switches will accept Class R fuses also. A field-installable rejection kit is available, which, when installed, rejects all but Class R fuses. See pages through 6 for Class R fuse kits.

14 Receptacle Switches Interlocked receptacle switches are furnished with a factory-installed threephase four-wire Appleton Powertite, Crouse-Hinds Style Arktite, or Hubbellock receptacle. The fourth wire is connected to the switch equipment grounding terminal and is not a solid neutral termination. Interlocking linkage between the receptacle and switch mechanism prevents insertion or removal of the plug while the switch is in the ON position, or insertion of any plug other than specified. The interlocking mechanism also prevents the switch from being turned ON if a plug has not been fully inserted into the receptacle. Appleton Powertite Receptacle H6AWA Interlocked Receptacle Switch with Appleton Powertite Receptacle Devices are UL Listed and CSA Certified, suitable for use as service equipment Receptacles are epoxy powder coated over copper-free cast aluminum A, H6AWA and HU6AWA are stock items.

17 NOTE: Heavy duty safety switches may be used on photovoltaic systems with a grounded feed. Refer to Figures 1B, 1D, 1F and (negative grounding shown; positive grounded systems are similarly allowed). For ungrounded systems, see National Electrical Code (NEC ) 690. (NEC 08, NFPA 70). Figure 1: Heavy Duty Safety Switches General dc and Photovoltaic Systems As a market leader and innovator in photovoltaic (PV) applications, we are proud to announce a catalog section dedicated to dc and PV safety switch applications. This section focuses on the Square D brand UL approved Heavy Duty Safety Switch dc and PV wiring schemes. Additionally a UL witnessed and Square D self-certified PV wiring option is presented. This additional unlisted option provides a robust, cost effective option for PV systems. All heavy duty safety switches with dc ratings (-, - and 4-pole fusible and nonfusible) are Underwriters Laboratories (UL) Listed and CSA Certified for use on dc applications when wired as shown in Figure 1 (A, B, C, D, E, and F). UL Listed, CSA Certified (Files E8 and E48). Additionally: Heavy duty safety switches are rated for 0 Vdc maximum open circuit voltage. Non-fusible safety switches may carry percent of the nameplate current rating. Fusible safety switches may carry 80 percent of nameplate current rating (continuous use). Heavy duty switches are dc horsepower rated as indicated on the safety switch wiring diagram. Heavy duty switches have a,000 ampere dc short-circuit rating at 0 Vdc unless otherwise stated on the switch wiring diagram. Consult factory for short circuit current ratings at Vdc.

Field-installed transparent barriers do not restrict visual inspection of the switch. Barriers provide IEC9 IPX finger safe protection when door of enclosed disconnect switch is open. Convenient door allows use of test probes without accessing fuses and replacement of fuses without removing barrier. Barrier can also be used with the skirt kit to enclose a panel mounted Type 94 disconnect.
