SPC 841B Test Jack Isolator Paddle

The Specialized Products 841B Test Jack Isolator Paddles are designed for temporary separation of series current-jack poles on test switches used for metering and protective-relay circuits. Insert this orange thermoplastic isolator into a series test jack (ABB/Westinghouse, GE FT, Superior, Meter Devices, and States) to isolate the two blades of the jack for testing. Bright orange color ensures high visibility, even in poor lighting.

Made of molded polycarbonate, these isolator paddles are extremely durable. Tough acetal resin has low coefficient of friction for easy use. The unit has a 5 mm (0.197 in) hole on the end for a key chain or cord. Total length: 89 mm (3.5 in), insertion length: 40 mm (1.6 in), width: 13.5 mm (0.5 in), blade thickness: 1.6 mm (0.06 in), handle/guide thickness: 4 mm (0.16 in).

Remember to remove all isolator paddles and restore switches to their normal operating state when testing is complete.
