Latest Patents

One of Gryctko's latest patents is titled "Combined fault current and applied voltage tripping for solid state trip." This invention discloses a solid-state trip circuit that utilizes a shunt path saturable transformer. The transformer is designed with a current transformer that has a relatively high resistance shunt, which applies input voltage to the transformer primary winding. As the input current increases, the voltage drop across the shunt also increases, leading to quicker saturation of the transformer iron. This saturation time during each half cycle provides a measure of the current flow in the primary line. The output from the secondary winding of the transformer, along with a direct resistive connection from the input circuit lines, is used to operate a circuit breaker trip latch. The energy for tripping at lower overload currents is derived directly from the line voltage, while at high overload conditions, tripping occurs through energy from the transformer.

Another significant patent is for "Auxiliary feature modules for circuit breakers." This invention includes both undervoltage and shunt trip auxiliary feature modules that can be mounted alongside circuit breaker modules. The design features an electromagnetic trip device with a trip actuator that is normally latched in a reset position. A lost motion connection links the actuator with a trip member, which engages the releasable latch for the automatic trip means of the circuit breaker. This innovative design ensures that when the actuator is released, the movement is transmitted to the circuit breaker latch for tripping. Each module also includes a reset member that automatically resets the actuator after each tripping operation.
