Isolating DC Circuits Has Never Been Easier or Safer The Cooper Bussmann® Quik-Spec™ Solar DC Safety Switch Provides the Extra Measure of Protection • Flexibility of Application Available in single-pole fused and non-fused versions, this 600Vdc safety switch is available up to 200A with NEMA 3R, 12 and 4X enclosures, making it easy to apply in solar power applications. Isolated ground terminals (neutral) for grounded conductors and ground lug for equipment grounding conductor included. • Enhanced Finger-Safe Design Large, clear polycarbonate deadfront is standard on all models, greatly reducing the possibility of accidental contact with live parts. It permits positive visual identification of switch state. • Meets UL and NEC® Requirements With multiple poles prewired from the factory with jumpers, these switches are listed to UL 98 and UL 50 standards. Marked as suitable for NEC® Article 690 PV applications up to 600Vdc per UL 1741 requirements. NEC® 690.14.(C) 2 required “PV System Disconnect” label included. • Flange Handle Operation Always in contact with the switch mechanism, the flange operated switch is preferred in most industries. Lockout/tagout provision accepts up to three padlocks to increase protection of workers. • Fast-Acting Fuses Remove Faults Faster On fused versions, install Cooper Bussmann® Solar Series PVS-R Photovoltaic Class RK5 fuses* for quicker fault clearing on PV systems. * Order fuses separately. NEMA 3R, 12 & 4X Enclosures with NEC® 690.17 Compliant Labels Factory Installed Jumpers and Neutral Make installation easier. Warns that the switch terminals may be energized when switch is in the open position. Door Interlock Prevents opening door while energized, but can be manually overridden for testing or inspection. Clear Polycarbonate Deadfront Covers energized parts to provide added protection against electrical hazards. Fused Version For Added Protection High Visibility Padlockable Handle Fuse clips located on switch center pole to ensure both clips are de-energized in OFF position. Meets NEC® 690.16 that requires isolating the fuse from all potential supply sources. Easy to operate with gloves and accepts up to three padlocks. Conduit Knockouts For easy installation.
