16 Page NX Fuses With rc-strangler Loadbreaking Device Features Eaton s Cooper Power Systems NX fuses with rc-strangler loadbreaking device offer: Safe loadbreaking. The rc-strangler loadbreak quickly extinguishes load-current arcs drawn between the mounting contacts and the fuse conductor during loadbreaking operation. Prevention from accidental closing. The rc-strangler loadbreaking device must be cocked before the fuse can be closed into the mounting. NEM standard hookstick operation. oth the pullring and the hinge accept the standard distribution-class hookstick. The hinge is made with a slot for the hookstick, making fuse removal from and replacement in the mounting easy. lown-fuse indication. red button is clearly visible after the fuse has operated. High-voltage warning. The big warning label (readable when the fuse is hanging open) warns personnel of possible danger. Optional latch. plastic latch that gives a positive indication that the device is armed is available as an accessory (See Page 15). Operating Principles The rc-strangler loadbreaking device is a springloaded sliding sleeve that cuts off the arc drawn between the mounting contacts and the fuse conductor when the fuse is opened while load current is flowing. pullring at the top of the fuse (for hookstick operation) and a hinge at the bottom complete the loadbreak device. The rc-strangler loadbreak is complete in itself no auxiliary loadbreaking tool is required and no additional loadbreaking switch in series is necessary. ll current magnitudes through the continuous-current rating of the fuse can be interrupted positively and safely under proper conditions. The loadbreaking assembly includes a stationary core and a sliding molded sleeve that covers the contacts on opening the hinged assembly. The sleeve is made of high-quality material that gives off small quantities of arc-quenching gases under the heat of the arc.
