Where is C type MCB used?

‘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.

What is a Type C MCB?

The level of this magnetic trip gives the MCB its type characteristic as follows: Type B – trips between 3 and 5 time full load current. Type C – trips between 5 and 10 times full load current. Type D – trips between 10 and 20 times full load current.

Which is the best MCB for home?

Here, the list of the top 10 best MCB brands in India.

• Legrand.
• Havells.
• Finolex.
• Siemens.
• Schneider.
• ABB.
• Orient Electric.
• Eaton.

What is the difference between Type B and Type C MCB?

Type B devices are designed to trip at fault currents of 3-5 times rated current (In). For example a 10A device will trip at 30-50A. Type C devices are designed to trip at 5-10 times In (50-100A for a 10A device).

What is B and C in MCB?

Type B devices are designed to trip at fault currents of 3-5 times rated current (In). For example a 10A device will trip at 30-50A. Type C devices are designed to trip at 5-10 times In (50-100A for a 10A device). Type D devices are designed to trip at 10-20 times In (100-200A for a 10A device).

What are Type C circuit breakers used for?

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.

How many amps does my house need?

Most homes require an electrical service of at least 100 amps. This is also the minimum panel amperage required by the National Electrical Code (NEC). A 100-amp service panel will typically provide enough power for a medium-sized home that includes several 240-volt appliances and central air-conditioning.
