How much ampere MCB required for 1.5 ton AC?

Hi there,

I want to share the definition of MCB before telling you about how much ampere MCB required for 1.5 ton AC. Do you wonder what will happen to circuit breakers if they are not installed properly? The devices will start burning. To avoid this miniature circuit breaker is used. Miniature circuit breaker helps to prevent these type damages. MCB is an automatic switch that provides excessive current flow through the circuit. This circuit breaker can be closed without manual replacement. If MCB is in a fuse, and it has been operated it should be replaced or rewired depending on the type of MCB. Therefore, this fuse is also known as a sacrificial fuse. This is the main reason why MCBs are used as an alternative to fuse.

Normally, MCBs for domestic installations  are usually rated at 6000 amps which allows them to over load the current. So, it is very important for us to learn how much ampere MCB required for 1.5 ton inverter AC. I will share a chart with you which will help you clear the doubts.

I hope you understand how much ampere MCB required for 1.5 ton AC.

An MCB, or Miniature Circuit Breaker, is an electrical device designed to protect electrical circuits from overloads and short circuits by automatically interrupting the flow of electricity when a fault is detected. It is hard to say which MCB is best for 1.5 ton AC without consulting with an expert electrician. We had installed an AC of 1.5 ton last year and that is when we learned about these aspects. 

How much ampere switch required for 1.5 ton ac?

To determine the amperage rating for a 1.5-ton air conditioner, calculate the current draw using the formula: Current (Amps) = Power (Watts) / Voltage (Volts). A typical 1.5-ton AC unit has a cooling capacity of around 4,500 watts and operates at 240 volts. 

So, 4,500W / 240V equals 18.75 Amps. To ensure safety and accommodate startup surges, a 20-ampere switch or circuit breaker is recommended for a 1.5-ton AC unit.

I hope this clarifies what AMP MCB required for 1.5 ton AC. You can also refer to this chart to decide your capacity, current in AMP and breaker size:
