Product Features
1. Working status indication 〈 green light for normal, red light for failure or fault
2. Beautiful structure, convenient installation
3. It is mainly used to protect the stable and safe operation of electrical equipment in thunderstorm weather.
4. The discharge current is high (20-200ka). Star structure, suitable for all kinds of wiring.
After fusing, the cause of fusing should be found out and the fault should be removed. The reason of fusing is short circuit or overload, which can be judged according to the situation of fusing.
When the melt melts under overload, the noise is not big, the fuse only melts in one or two places, the variable cross-section melt only melts in a small section, and there is no burning phenomenon in the fuse tube.
When the melt is burnt out under short circuit, the sound is very loud, the melting part is big, and there is burning phenomenon in the melting tube. According to the cause of fusing, find out the fault point and remove it.
When changing the melt, the specification of melt should be suitable for the nature of load and line current.

FAQ
Q1: How do I know if my surge protector is bad?
A1: on cheap SURGE protectors, the only way to tell if they are going bad or not is if the light starts flickering in the switch. There’s a metal oxide varistor on the back side of the switch that provides the surge protection, along with a collection of capacitors. It also drives the light in the switch.
Q2: Should my refrigerator be on a surge protector?
A2: We do not recommend connecting a refrigerator or freezer to a surge protector. The compressor is sensitive to temperature and current overloads, and will shut itself down with a surge. … A surge protector will override this system, and if there is a power surge, your refrigerator may not restart.
Q3: What causes a power surge in your home?
A3: Lightning strikes are a common cause, but most power surges stem from inside your home. … Power surges occur when the flow of electricity is interrupted, then started again, or when something sends electricity flowing back into the system.
Q4: Can surge protectors catch fire?
A4: Every year, thousands of fires result from surge protectors, power strips and electrical cords. … frayed wires, or has a unit that is not working properly, should be replaced immediately. • Do not plug a surge protector or power strip into an existing surge protector or. power strip.
Q5: Is it dangerous to plug an extension cord into a surge protector?
A5: Using an extension cord with a surge protector is a fire hazard at worst, and at best runs the risk of damaging or degrading the cords of either component. … Don’t use a high-current surge protector with a low-current cord, and if one component uses a 14-gauge wire, the other should as well.
