Miniature circuit breakers commonly known as MCB, are mechanically operated switches cum circuit protection devices. It is an electro-mechanically operated automatic circuit protection device and is used to interrupt a circuit during overload and short circuits. It can be used as an alternative to fuses for domestic applications. Hi, I hope you can help. I am in the process of completing our first solar panel installation and am using the SMA (sunny boy 2000) inverter. We are installing ten panels. Can anyone confirm whether we should use a type B or type C 16A MCB for the consumer unit. Thank you. The global ac mcb market was valued at $2.2 billion in 2022, and is projected to reach $3.8 billion by 2032, growing at a CAGR of 5.5% from 2023 to 2032 The highest star rating of an air conditioner is 5, and the lowest star rating is 1. A 5-star air conditioner will cool your room in the most efficient manner compared to a 1 or 2 Star Rated air conditioner. Simply put, a 5-star AC to cool a room faster, while using less electricity than a 1 or 2-star AC. According to technical specifications in this link, input current at 230 VAC is 0.5 Amps. So, if you will use this voltage selection, you have to use a MCB with rating greater than 0.5 A. 0.63 or 1 A will be fine. And for inrush current, it is stated in the technical specifications 63A;Full width at half maximum 1 ms, The best-suited type of MCB for domestic appliances, where the current load is medium, is type C. Type C MCB trips off when the flow of current is 5-10 times more than normal. Type D MCB has a high resistance as they can withstand up to 10-20 times the current rate. CfRJ4cF.
