The distinction between AC and DC contactors depends essentially on whether the load end is used for AC or DC. Now there is a part of the AC contactor control coil is DC, the suction electromagnet is also DC electromagnet,

In the power system, circuit breakers, contactors and relays seem to be familiar to people, but many people know little about them, but they do not know the difference and what the connection is. Let’s talk about them. First, the

Photovoltaic circuit breaker adopts special arc extinguishing and current limiting system, which can quickly cut off the fault current of DC distribution system, so that the level difference coordination can be greatly improved. Photovoltaic circuit breaker is especially aimed at

DC circuit breaker can be used to distribute electric energy, do not frequently start asynchronous motor, power line and motor protection, in normal circumstances on and off the circuit, but also can be used to remove the short circuit fault

Power system: Small dc circuit breaker in the power plants, substations and other large capacity, high voltage, dc system for relay protection in power system, operation control, signal and emergency lighting audio equipment to provide reliable power supply, dc circuit

As of today, there are still many customers in the choice of AC and DC universal products, has been the AC protection circuit breaker for DC system protection, due to the particularity of DC system, such application will make the

Photovoltaic industry in the past today or “sorrow”, but this year has been the “peak of the road”! Because of the photovoltaic industry “warming” demand is gradually increasing, however, with the increase in the demand for DC circuit breakers, more

DC circuit breaker is an important part of grid-connected photovoltaic power generation system The trait of the grid photovoltaic power generation system is solar battery components produced by direct current through the grid inverter converted to meet the requirements of

Distribution circuit breaker refers to the circuit breaker specially used for distributing electric energy in low-voltage network, including power supply main switch and load branch switch. In the selection of such circuit breakers, in addition to following the general selection

1. Installation should be carried out according to the specified position, so as not to affect the performance of the action. In the installation of leakage protector with short circuit protection, it is necessary to ensure that there is enough
