Solid state circuit interrupter

A circuit interrupter structured to be electrically connected between a power source and a load, the circuit interrupter comprising:

• a frame including a number of compartments;
• a number of solid state switch assemblies, each solid state switch assembly disposed in a corresponding one of the number of compartments and including:
• an input terminal;
• a first conductor;
• an output terminal;
• a second conductor;
• and
• a solid state switch module electrically connected to the input terminal with the first conductor and electrically connected to the output terminal with the second conductor and including at least one solid state switch and a sensor;
• a tripping device structured to trip the circuit interrupter to interrupt current flowing to the load in an event of a fault;
• and
• a gate driver circuit including a desaturation function (DESAT) function output and structured to control a state of the solid state switch module based on a trip signal from the tripping device and a change of the DESAT function output to an on state, wherein the DESAT function output changes to the on state when the current flowing through the solid state switch module reaches a first threshold level,
• wherein the sensor comprises a current sensor structured to sense current flowing through the circuit interrupter, the current sensor having a normal sensor output proportional to the current flowing through the circuit interrupter and an over current detection (OCD) output that changes to an on state when the current flowing through the circuit interrupter reaches a second threshold level.
