Circuit Breakers and Switches Detecting electrical problems and preventing accidents.
The circuit breakers and the switches protect wiring in case of electric abnormality such as overcurrent and short circuit, and prevent accidents.
The core of circuit breakers is reliability. By conforming to JIS, ISO 9001 and other standards, we constantly strive for the highest reliability in developing and manufacturing our products.
