Title: Innovations of James P Ellsworth

Introduction

James P Ellsworth is a notable inventor based in Beaver, PA (US), recognized for his contributions to electrical engineering. He holds a total of 8 patents, showcasing his innovative spirit and technical expertise in the field.

Latest Patents

Among his latest inventions is the "Electrical switching apparatus employing twice-energized trip actuator." This circuit breaker features separable contacts that can move between closed and open positions to switch electrical current. The operating mechanism facilitates this movement, while a sensor detects the electrical current and generates a corresponding sensed current signal. A shunt diverts a portion of the electrical current, and a trip mechanism uses the sensed current signal to create a trip signal. The trip actuator, which includes a trip solenoid energized by the trip signal, also incorporates loops energized by the shunted current.

Another significant patent is the "Current limiting circuit interrupter with insulating wedge." This device is characterized by a circuit interrupter structure housed within an insulating casing. It features a mechanism for opening and closing separable contacts, which are mounted on contact arms that are spaced apart to create a current-limiting relationship. This design ensures that any arc formed between the opening contacts is directed away from the contact arms. Additionally, a dielectric plate-like shutter moves into the gap between the separating contacts when they open, and a reset structure retracts the shutter when the contacts close.
