Prepaid electric meter with delay circuit breaker points the working voltage of the shunt tripping the circuit breaker characteristics for 70% to 110% of the scope of any value when used through signal lines to the intelligent breaker and shunt tripping device pole exert a control on the voltage, the signal voltage by remote control circuit or IC card electric meter) and then the circuit breaker handle pushed to a closed position for closing.
DZ47-63 electric power circuit breakers, suitable for electric motor vehicles, single pole rated voltage DC 12V~64V, rated current to 63A line in the overload, short circuit protection, but also can be used in normal circumstances do not frequent power and electric devices and electric vehicles lighting circuit.
This product conforms to GB10963.1, IEC60898-1 standard.
Current circuit-breaker (residual): the circuit in which the leakage current exceeds a predetermined value can automatically switch. Commonly used leakage circuit breaker is divided into two types of voltage and current, while the current type is divided into two kinds of electromagnetic and electronic. Electric leakage circuit breaker is used to prevent electric shock, which should be chosen according to the different requirements of direct contact and indirect contact with two kinds of electric shock protection.
YDM1 series plastic case circuit breaker, is the use of international advanced design, manufacturing technology, the development of new circuit breakers. Its rated insulation voltage of 690V, suitable for AC 50Hz, rated working voltage 400V and below, rated working current 800A and below the circuit for the use of non frequent switching and motor without frequent starting, circuit breakers with overload, short circuit and under voltage protection device, can protect lines and power equipment is not damaged.
The isolation switch is a kind of electrical appliance in the high voltage switch. It is the working principle and structure of the circuit which is isolated from the circuit. However, the use of large amount, high reliability, the design, construction and safe operation of the power plant are all great. The main characteristic of the knife gate is the ability to have no arc suppression, and can only be divided into the circuit without load current.
