New circuit breaker and switch combination for protection of air-conditioning systems.Design engineers today are trying to systematically reduce individual components, which is a key factor of cost-effective design.Normally less components also means more space which is enabled by the design of compact products, in order to support Design Engineers in their research for parts reduction, we offer a combination of circuit breakers and switches, these are circuit breakers providing overload protection and serve as an On/Off switch of devices, machinery and equipment at the same time.
