the function of low voltage circuit breaker thermal releasethe tripper is a device mechanically connected to the circuit breaker to release the retaining mechanism and automatically disconnect the circuit breaker. its function is that when the line has leakage or personal shock, the current vector through the zero sequence current transformer is not equal to zero. voltage is generated on both sides of the secondary coil of the transformer.

difference between air switch and molded case circuit breaker

processing method for resisting jump of molded case circuit breakerwhen the operation of load interruption and power system failure occur in substation, the key equipment is high-voltage circuit breaker, which directly affects the normal operation of the entire power distribution system, is the most vulnerable link in high-voltage power supply and distribution system, and many factors affect the normal operation of high-voltage circuit breaker.

accessories of molded case circuit breaker

causes of coil burning of molded case circuit breakerin the process of using plastic case circuit breaker, coil burnout often occurs. here are the reasons for coil burnout and how to prevent coil burnout.

Detailed Explanation of Current Limiting Technology for DC Molded Shell Circuit BreakerWhen the short circuit current is interrupted, a fast-growing arc, usually called dynamic arc resistance, will be generated in a manicure circuit breaker. Maintaining stable arc combustion requires a certain voltage, and the "dynamic arc resistance" is equivalent to a thousand series resistors in the circuit.

introduction of common circuit breakersbefore purchasing circuit breakers, we must make clear the classification of circuit breakers, so that when purchasing, it will not be very entangled. here are some common circuit breakers in life.

differences between molded case circuit breakers and miniature circuit breakersplastic case circuit breaker mainly provides protection function for overload and short circuit in low voltage distribution system and motor protection circuit. because of its reliability and stability, it has become a widely used product in industry. miniature circuit breaker is also a circuit breaker product with great use range and quantity. its main function is to provide protection for distribution devices of building electrical terminals. both of them belong to circuit breakers. many people are confused and do not know how to choose relays. here is a brief introduction of the differences between them.

brief introduction and protection ability of molded case circuit breakerplastic case circuit breaker, also known as device circuit breaker, all the internal parts are enclosed in a plastic case, the internal components are modular, with strong sectional ability and isolation protection ability. next, we will introduce the main functions and functions of the plastic case circuit breaker.

how to choose an appropriate circuit breakernowadays, circuit breakers are used more and more widely. they can protect circuit in daily life. when the circuit is short-circuited or overloaded, the current will be cut off automatically, which greatly reduces the risk of electric fire in life. in the choice of circuit breakers, many people do not know how to choose the right circuit breaker. here is how to choose the right circuit breaker for you.

common problems and solutions of molded case circuit breakerlow voltage circuit breaker, also known as air circuit breaker. mainly used for automatic disconnection circuit and power cut-off under abnormal circumstances such as overload, short circuit and under-voltage. in the process of using air circuit breaker, we often encounter some problems. here we introduce the common faults and solutions of low voltage circuit breaker.

what is the principle of plastic case circuit breaker?low voltage circuit breaker (hereinafter referred to as circuit breaker) is a kind of switching device which can not only connect and break normal load current and overload current, but also switch on and break short circuit current. low-voltage circuit breaker not only plays a control role in the circuit, but also has certain protective functions, such as overload, short circuit, under-voltage and leakage protection. it can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. widely used in the life, industry, electrical industry.
