Miniature Residual Current Circuit Breaker

Miniature Residual Current Circuit Breaker, Ceho provides you with a class of electrical safety devices that can detect and cut off electrical circuits when there is leakage in the circuit. Also in this function, it can protect personnel and equipment from electric shock, fire hazards, or other hazards caused by line failure, insulation failure, or accidental contact with live parts.

This product works on the basis of Kirchhoff's current law, which means that the total current flowing into the node equals the total current flowing out of the node. The live and neutral currents in a normal circuit are balanced. But if a fault occurs, some of the current flows to earth.The RCCB is able to detect this imbalance and react quickly to trip and open the circuit.

Inside it, there is a toroidal transformer with three coils, which are the live coil, the neutral coil and the induction coil. When the currents are balanced, the live coil and the neutral coil produce equal and opposite magnetic fluxes. On the contrary, when unbalanced, residual magnetic flux will be generated, so the voltage induced in the induction coil triggers the relay to open the contacts of the residual current action circuit breaker to complete the circuit.

Key Points of Our Products

·Miniature Residual Current Circuit Breaker: A safety device that detects and breaks a circuit when there is leakage current in the circuit.

·Principle of operation: Kirchhoff's current law, as mentioned above, detects imbalance between live and neutral and trips to prevent danger.

·Type: RCCB can be divided into AC, A, B and F types, suitable for different leakage currents and applications, if necessary, you can contact us for selection advice, we will help you fully consider the load type, rated residual operating current (I Detail n), rated current (In) and the number of poles required for the circuit, and then make judgments and recommendations.

·Advantages: RCCB provides the necessary protection against electric shock and fire, supports various types of currents and loads, and is easy to install and maintain.

Miniature Residual Current Circuit Breaker has a test button that checks function by generating a small leakage current. When the button is pressed, the live wire on the load side will be connected to the zero line of the power supply, bypassing the zero line coil, and the current will be unbalanced, and the trip will be triggered under normal circumstances. If there is no trip, it may be an RCCB fault or wiring error requiring repair or replacement.

Product Types

We have mentioned different types of Miniature Residual Current Circuit Breakers before. Ceho will introduce them to you in detail so that you can choose them conveniently.

● Type AC: only responds to pure alternating current.If you want general purpose applications with electronic equipment or inverters that do not produce DC or pulsating currents, choose it.

● Type A: Responsive to AC and pulsating DC.There are electronic devices that generate rectified or chopped current, such as computers, televisions, or LED lights, which are suitable for use.

● Type B: Respond to AC, pulsating DC and smooth DC. It is suggested that there are devices that generate smooth DC power to use, and solar inverters, battery chargers and electric vehicles are more common in our cooperation.

● Type F: Responds to AC, pulsating DC, smooth DC and high frequency AC up to 1 kHz. Suitable for frequency converter, induction cooker or dimmer, etc. will produce high-frequency current equipment.
