Title: Hiroaki Fugihisa: Innovator in Circuit Interruption Technology
Introduction
Hiroaki Fugihisa is a notable inventor based in Fukuyama, Japan. He has made significant contributions to the field of circuit interruption technology, holding a total of 2 patents. His work focuses on enhancing the safety and efficiency of electrical systems.
Latest Patents
Fugihisa's latest patents include a circuit interrupter and a multi-pole circuit interrupter. The circuit interrupter features an automatic trip unit that connects to an interrupting unit. This design allows for the tripping of the interrupting unit to open separable contacts in response to an overcurrent. The automatic trip unit is a replaceable unit selected from various types, including electronic and thermally responsive electromagnetic trip units.
The multi-pole circuit interrupter consists of a first pole unit with an operating mechanism and a second pole unit without one. Each pole unit includes a movable contact, a stationary contact, and a contact arm assembly. The first contact arm in the first pole unit has an elongated guide hole that connects directly to the operating mechanism. The second contact arm features an elongated hole that allows for a spring-biased sliding pin to extend through both holes. This design creates a time delay between the resetting movements of the sliding pin in the first and second pole units, enhancing the functionality of the interrupter.
