Technical FAQs 4

What is a 3 phase circuit breaker?

Three-phase circuit breakers: Predominantly used in larger homes, commercial or industrial settings where large amounts of power are required. These breakers interrupt power in three separate live wires, making them ideal for systems that demand a high power supply.

What does a circuit breaker do?

A circuit breaker is an automatic safety switch that stops the flow of electricity when it detects a problem, such as an overload or short circuit. This helps protect your wiring and appliances from damage while reducing the risk of electrical fires.

Who invented a circuit breaker?

The circuit breaker concept was first patented by Thomas Edison in 1879 as a device used to protect his electric lighting system. Over the years, circuit breaker technology has made many improvements and innovations. For instance, in the early 20th century, oil circuit breakers were common, using mineral oil to insulate and extinguish the arc.

What is a b curve circuit breaker?

B Curve Circuit Breakers: B curve circuit breakers trip when the current reaches 3 to 5 times the rated current. They are ideal for resistive or slightly inductive loads where the surge current is not significantly greater than the rated current. This makes them suitable for applications like lighting circuits.
