DEFINITION

Classification: 102/202.3

Fuse device resistive shunt:

(under subclass 202.1) Subject matter wherein the device includes bare lead wires and a resistive shunt connected between the wires or between a wire and a casing of the device so that the bulk of the current caused by accidental abnormal voltages is diverted through the shunt to prevent the ignition of the device.

(1) Note. The shunt may or may not be removed when the device is energized.

(2) Note. The shunt, per se, is here.

(3) Note. The term "lead wires" include terminals.

(4) Note. Here the resistance of the shunt is fixed.
