What does D mean on circuit breaker?

This is the minimum current at which the circuit breaker will discontinue the flow of electricity, or trip. It does this to protect devices plugged into the circuit from sudden rises in levels of current.

WHAT IS curve type in MCB?

‘C’ Curve MCB is used for the protection of circuits with equipment that cause surge current i.e. low-HP motors used for air-conditioners, small mono block and submersible pumps with mainly Inductive Load. Finolex’s B and C Curve MCB’s are a safe and trusted brand for those looking for the best electrical solutions.

What is the meaning of C20 in MCB?

Catalog Description: S802N-C20 High Performance MCB. Long Description: The S802N-C20 is a 2-pole High Performance Circuit breaker with C-characteristic, with cage terminal and a rated current of 20 A. It is a current limiting device with a maximum breaking capacity of 36kA at 240/415V.

What is D curve?

This type of MCB trips between 10 and 20 times full load current. These MCBs are use in specialty industrial / commercial uses where current inrush can be very high. The common applications include transformers or X-ray machines and electric motors.

What is a curve breaker?

MCB (Miniature circuit breaker) is a re-settable device designed to protect a circuit from short circuits and overcurrents. The trip curve of an MCB’s (B, C, D, K and Z curves) tell us about the trip current rating of Miniature Circuit breakers.

What is C25 in MCB?

Catalog Description: S803N-C25 High Performance MCB. Long Description: The S803N-C25 is a 3-pole High Performance Circuit breaker with C-characteristic, with cage terminal and a rated current of 25 A. It is a current limiting device with a maximum breaking capacity of 36kA at 240/415V.

What are D curve circuit breakers used for?

What is Type C breaker?

Type C circuit breakers are used for more powerful electrical devices where any surges are likely to be higher – typically commercial and industrial environments. They are designed to trip at currents between five and ten times their rated load. Good examples include smaller electric motors and fluorescent lighting.

What does C10 mean on a circuit breaker?

Long Description: The S801N-C10 is a 1-pole High Performance Circuit breaker with C-characteristic, with cage terminal and a rated current of 10 A. It is a current limiting device with a maximum breaking capacity of 36kA at 240/415V. It can be used for voltages up to 400/690V and in DC as well.
