Tripper is an accessory for remotely operated tripping. When the power supply voltage is equal to any voltage between 70%-110% of the rated control power supply voltage, the circuit breaker can be reliably...
Leakage circuit breaker is mainly composed of zero sequence current transformer, electronic component board, leakage release and circuit breaker with overload and short-circuit protection. The leakage
The input pins of multiple SSRs can be connected in series or in parallel, but if each SSR must meet the high level, the zero-crossing type trigger current is greater than 5mA,
Solid state relays are non-contact electronic switches with isolation function, and there are no mechanical contact parts in the switch.
AC contactor function introduction:The AC contactor is an intermediate control element, and its advantage is that it can frequently turn on and off the line, and control a large current with a small curren...
Nowadays, there are many electrical accessories on the market, each of which has a certain range of use and functions, and contactors and relays are the two types that are easy to confuse. So, what is the ...
The main function of the general isolation switch is to disconnect small currents and change the operation mode. I don't know if you have found it or not. One of them is to disconnect the small current, wh...
Electrical fire is the "first killer" that threatens people's life and property safety. According to statistics, nearly half of the fires in my country are caused by improper use of electricity. With
A DC isolating switch is a device for preventing the short circuit between AC and DC of the DC isolating switch.
Introduction to ContactorsContactors are divided into alternating current contactors (voltage AC) and direct current contactors (voltage DC), which are used in electric power, power distribution and p
Instructions for use of relaysRated working voltage: refers to the voltage required by the coil when the relay works normally, that is, the control voltage of the control circuit. Depending on the mod
Fuse refers to an electrical appliance that fuses the melt with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. The fuse is a current protector m
