B Type, C Type and D Type Circuit Breaker

First, I will discuss what is the circuit breaker. A circuit breaker is a device or equipment which can,

  • Make or interrupt a circuit either manually or by remote control under normal conditions.
  • Break a circuit automatically under fault conditions.
  • Make a circuit either manually or by remote control under short circuit or overload conditions.

C Type Circuit Breaker

How to identify type c circuit breaker ?. If you buy 32 Amps circuit breaker from the market front side there will be printed as C 32 by seeing this you can easily identify a c-type circuit breaker.

The c-type circuit breaker has minimum tripping current 5 to 10 times the rated current (for example: assume a rated current of the circuit breaker as 5 amps when 25 amps current flow through circuit breaker it will trip). Now let’s see applications of a c-type circuit breaker, this type of circuit breaker is used for loads with a moderate inductive component which uses low-hp motors or specific types of lighting like air conditioners, residential or commercial pumps, fans and also lighting which uses ballasts with an inductive component.

B Type Circuit Breaker

How to identify type b circuit breaker ?. If you buy 32 Amps circuit breaker from the market front side there will be printed as B 32 by seeing this you can easily identify a b-type circuit breaker.

The b-type circuit breaker has minimum tripping current 3 to 5 times the rated current (for example: assume a rated current of the circuit breaker as 5 amps when 15 amps current flow through circuit breaker it will trip). The b-type circuit breaker is used for purely resistive loads or loads with a very small inductive component.

The purely resistive loads are the loads that use heating elements such as the heater, toasters maker, etc. This is also used in lighting circuits (non-inductive) and also for general purpose outlets.

D Type Circuit Breaker

The d-type circuit breaker has minimum tripping current 10 to 20 times the rated current. This type of circuit breaker is used for loads with a very high inductive component, typically found in industrial settings.

This type of circuit breaker is connected with large induction motors or transformers, X-ray equipment, and welding equipment.

I hope this article may help you all a lot. Thank you for reading. If you have any doubts related to b type, c type and d type circuit breaker, then comment below.
