The residual current circuit breaker is one of the important electrical equipment in the low-voltage power distribution system. It is a switching device used to cut off and distribute the overcurrent and short-circuit faults generated in the circuit. oxidation reaction to extinguish the arc.
What is the difference between residual current circuit breaker and leakage protector?
What is the structural composition of residual current circuit breaker?
What is the actual use value of residual current circuit breaker?
residual current circuit breaker (or protection device) is a series of electrical products, which includes residual current circuit breakers (now called residual current circuit breakers). The leakage protection circuit breaker (now called residual current circuit breaker) is a certain variety of the leakage protector (or protection device) in this series of electrical products. The former is a series of products, and the latter is one of the products of the series.
The leakage protector only has the function of leakage tripping, which is used to effectively protect the direct contact and indirect contact of the low-voltage power grid. It can also be used as the phase loss protection of the three-phase motor. The leakage protector generally has a small rated current and can directly protect an electrical appliance! In addition to the leakage tripping function, the leakage circuit breaker also has an overcurrent tripping function; that is, it includes leakage, overload, short circuit, and some have an overvoltage protection function; the rated current of the general leakage circuit breaker is large, which is suitable for the whole circuit. Line protection!
1. Housing of the residual current circuit breaker:
Made of steel plate and painted with anti-rust paint;
2. The base part of the residual current circuit breaker:
1 fixed base; 2 movable movable bases; 3 mounting screws; 4 fixing bolts; 5 springs; 6 insulating plates.
3. Operating mechanism of residual current circuit breaker:
1 manual controller, 1 set of electromagnet components, 4 pull wires, 3 handles, 2 power lines, 1 signal line; 1 set of indicator light components.
1. A residual current circuit breaker must be installed at the construction site and the electrical equipment of temporary lines.
2. A residual current circuit breaker must be installed for hand-held power tools (except Class III), mobile household appliances (except Class III), other mobile electromechanical equipment, and electrical equipment with a high risk of electric shock.
3. Places with humidity, high temperature, large metal occupancy factor and other places with good electrical conductivity, such as production workplaces in mechanical processing, metallurgy, chemical industry, shipbuilding, textile, electronics, food processing, brewing and other industries, as well as boiler rooms, water pumps Auxiliary places such as rooms, canteens, bathrooms, hospitals, etc., must install residual current circuit breakers.
JIELI Electrical has been based in the low-voltage circuit breaker industry for nearly 20 years. Committed to the research and development, production, and supply chain management of MCB, RCCB and related supporting products.
