Circuit Breaker (Miniature Circuit Breaker)

         A small breaker is often used in buildings. Installed as a protective device with a load center or consumer unit in a low-current short circuit. A circuit breaker that can not be set to break current. And most of them are based on thermal and magnetic disconnection via mechanisms.

         For selecting the MCB for the consumer unit. We can install these two protection devices: the mains or main circuit breaker and the circuit breaker. Mostly, it is about 100 A for the MCB. The current selector circuit depends on the load at each point of use, such as light load, load socket, refrigeration load and water heater load, etc. The value of the I, the Icu value, and standards are the factors that must be considered before purchasing. Usually shown in kA RMS format.

Circuit Breaker (RCD: Residual Current Devices)

         Electrical appliances are everyday facilities. But do not forget that the dangers of electrical appliances. Can be fatal as well. So we should know the machine. Cut off leaks or RCD to prevent potential damage.

         Power cut RCD (Residual Current Devices) is a circuit breaker that automatically switches off the circuit when the input current is not the same, such as when people are exposed to electrical appliances with a leakage current. This device automatically cuts off the power. No loss occurs. Mainly, the benefits of RCD are to prevent the risk of fire, to prevent fire from electric leakage in the circuit or electrical appliances. Check to see if there is any leakage. Will continue to edit

         There are three types of circuit breakers: RCCB (Residual Current Circuit Breakers), RCBO (Residual Current Circuit Breakers with Overload Protection) and ELCB (Earth Leakage Circuit Breaker)

RCCB (Residual Current Circuit Breakers)

         Is a circuit breaker This helps to cut off the electrical circuits in the event of an electrical leakage but can not cut off the short circuit. Mostly used are two sizes together, 2 pole for one phase and 4 pole for 3 phase. In operation it is used in conjunction with MCB, MCCB.

RCBO (Residual Current Circuit Breakers with Overload Protection)

         It is equipped with a power supply (fire) with integrated circuit breaker. Can circuit breaker in case of leakage and short circuit.

ELCB (Earth Leakage Circuit Breaker)

         The electrical equipment was made. The main purpose is to protect the power supply or leakage. Mostly used to control the air conditioner, water pump, etc. The overall appearance is similar to the safety of the breaker is different. The ELCB has a small button called the TEST button, but the safety breaker has no TEST button. And the principle of operation and purpose of the application is different.

         The ELCB circuit breaker is designed to automatically cut or disconnect the circuit when a leakage occurs to the ground. The ELCB circuit breaker can not be disconnected if the current exceeds the specified rating. For example, on the ELCB, specify the current rating at 30 A If the current is exceeded, if the circuit breaker is normal, it will disconnect the circuit when the current exceeds the specified current. But in case of ELCB coordinates It is listed on the maximum tolerable it will not value it will release cycle. The maximum current flowing through the ELCB will cause it to break down without any decay. ELCB is suitable for use. To control and prevent risks only with electrical appliances. We know the maximum electricity consumption such as water heater, water heater, etc.
