Fusemate
A compact and reliable hand-held tool to make LV fuse replacement safe and avoid personal injury. The Kelman Fusemate closes the faulted circuit and displays the current lowing. The operator is a safe distance away using remote control. Fusemate has a fuse in series with a miniature vacuum switch. Its control and monitoring electronics provide the indication and control functions.
How Fusemate works
Use of Fusemate gives the operator crucial information to enable him to deal with the circuit safely. When closed under ‘Normal load’ current conditions the Fusemate will complete the circuit and display the current level on the LED bar graph display. When closed under ‘Fault’ current conditions, the fuse in the Fusemate blows to provide automatic protection for the operator (for abnormal currents where the fuse has not blown, the operator can open Fusemate). The trigger mechanism in the Fusemate is designed to give a uniformly controlled opening operation which is independent of the operator action and can safely interrupt up to 2kA.
