An early form of circuit breaker was described by Thomas Edison in an 1879 patent application, although his commercial power distribution system used fuses. Its purpose was to protect lighting circuit wiring from accidental short circuits and overloads. In 1924, a miniature circuit breaker — similar to the ones now in use — was patented by a Swiss ...
Being an inventor, Stotz and his team continued to push circuit technology further. In 1928 they developed a special circuit breaker for coping with loads of higher starting currents, including motor applications. This opened the door for industrial applications that nowadays can withstand the harshest of environments, such as dust, humidity and co...
However, with demand for resilient power 24/7 accelerating at breakneck speed, even the small but perfectly formed circuit breaker has some limits in today’s world. Unfortunately, such is the demand for power, outages and supply shutdowns are still a concern for operators of medium and low voltage switchgear. Such scenarios are not only financially...
While safety has been the critical driver behind circuit breaker technology since its invention, today, businesses of all sizes are also challenged with adopting sustainable operations. Taking the VD4 evo as an example, its ultra-compact design and energy efficient operation is fully Environmental Product Declaration (EPD) certified. It is 15% smal...
- AC Circuit Breaker. An AC circuit breaker is a safety switch usually built into your home’s electrical system. It looks like a switch that helps to stop the flow of electricity to any component or device that consumes a lot of power.
- High Voltage Circuit Breaker. Large power transmission networks are usually controlled by high-voltage type circuit breakers. This type of circuit breaker is used with a voltage rating of more than 600 volts.
- Low Voltage Circuit Breaker. A low voltage circuit breaker is suitable for circuits rated at 600 volts or less. The most commonly used low-voltage circuit breaker is a molded case circuit breaker.
- Miniature Circuit Breaker. These types of circuit breakers serve as a substitute for fuses and are used to protect the circuit from excess current. Miniature circuit breakers are automatic switches that opens when the current flowing through them exceeds the value for which they are set.
