3 . 5. Trapped Key Interlock Systems Available only on heavy-duty and safety switches. Trapped key systems are used on safety switches to prevent unauthorized operations or to predetermine a series of power transfers by an authorized operator. Before system construction can begin, the following information must be provided to the Flex Center: User name, address and telephone number Complete coordination (lock scheme) required with order To order, add Suffix TK to the standard catalog number. Example: DH363FWKTK. Item 5 Switch Type Heavy-duty Double-throw 6. Upper Cover Viewing Window Upper viewing window is centered over the switching contacts to provide visual verification of ON/OFF status. Available on most heavy-duty NEMA X stainless steel and NEMA 2/3R and doublethrow enclosures. Not available on non-metallic enclosures. To order, add Suffix W to the standard catalog number. Note: 30 00A window switches are now provided with a full view cover window for blade verification and blown fuse indication. 7. Lower Cover Viewing Window Lower viewing window is positioned over fuses and provides visual verification of blown fuse indicators for Littelfuse, Inc. fuses. Available in 200 A, twoand three-pole heavy-duty NEMA X stainless steel and NEMA 2/3R enclosures. Not available on nonmetallic enclosures. To order, add Suffix LW to standard catalog number. Note: 30 00A window switches are now provided with a full view cover window for blade verification and blown fuse indication. Items 6 and 7 Viewing Window (Upper or Lower) Contact the Safety Switch Flex Center for lead-time. 8.

The total price is the standard switch price plus the price adder. Example : DT36URKN non-fusible, three-pole, 30A switch with factory-installed neutral assembly. Example 2: DT363NRK fusible, three-pole, 00A switch with factory-installed neutral assembly. 9. Class R Fuse Clips Factory Installed for Heavy-Duty Switches Item 9 Voltage and and and and and 20 and To order, add Suffix 5 to the standard catalog number for 20V application. Add Suffix 6 to standard catalog number for V application. Total price is the standard catalog number price plus the price adder from the table above depending on the number of safety switch poles. Example: DH32FRK5 heavyduty, three-pole, 200A switch at 20V with factory-installed Class R fuse clips. 0. Class T Fuse Clips Factory Installed for Heavy-Duty Switches Item 0 Voltage To order, add Suffix T to the standard catalog number (catalog number identifies voltage). Total price is the standard catalog number price plus the price adder depending on the number of safety switch poles. Example: DH36FGKT heavyduty, three-pole, 200A fusible switch at 80V with factoryinstalled Class T Fuse Clips..
