Abstract
An electrical protective device that includes a reset mechanism uses a resistor body to act as a hold-off to a spring driven lockout for the reset mechanism. Upon the failure of an internal component of the protective device, the spring driven lockout mechanism is released by I.sup.2 R thermal action which causes a resistor to burn in half, or in the alternative, to melt solder mounting the resistor, thereby eliminating the hold-off and locking out the reset mechanism.
