PSU short circuit tester protection socket

Product introduction:
When repairing PSU power supply/server power supply/switching power supply or faulty electrical equipment, if the fault is not completely eliminated, powering on again after replacing the parts may cause damage to the equipment again, and in severe cases, the scope of the fault will be further expanded.
It is recommended to use a short circuit tester to protect the socket. In case of load short circuit, it will prompt and protect the circuit from secondary failure.

The scope of work:
Current: 20A
Voltage: 220V

Please note:
This product is not suitable for the working voltage obtained after the inverter output.
Kind tips:
This listing does not include bulbs as they are fragile, please purchase tungsten bulbs locally (LED lights are not allowed)

Instructions for use of protective socket
Before turning on the power, please switch the (maintenance switch) to the (maintenance position), and then connect the equipment to be repaired to the socket.
Turn on the main power to check the status of the bulb:
1. Full light means short circuit.
2. No light or slight light means normal. At this time, the (maintenance switch) can be switched to (working position) for other fault maintenance

The main function of the circuit breaker switch is equivalent to the switch,
Only under certain conditions will it be automatically disconnected (need to exceed the standard current of the circuit breaker, the incoming line must be thickened, and the incoming line fuse must be thickened). Generally, if the load is short-circuited, the fuse on the socket will blow first.
If there are other open circuit breakers on the front end it can also be tripped.
Therefore, this model is not really short circuit protected, so it is recommended that you must use it in the maintenance position (i.e. not connected to the circuit breaker)
