Collective earth leakage detection device LSG-6TB
Hikari Shoko Co., Ltd.
About This Product
■Features
・There are two models: one for 6 circuits and one for 10 circuits.
- The detection unit and space unit are plug-in type, making it easy to add or remove circuits.
・Although the operating display and output contact are automatically reset, once it has operated, it has an operating display function that continues to indicate that it has operated.
・Unlike the selector method, even if leakage occurs in multiple circuits at the same time, each circuit operates individually.
・Each detection unit has a test switch, so you can check the operation of each unit individually.
・The operating time of the detection unit is 3-point switching: 0.8 seconds, 3 seconds, and 5 seconds.
・Please use the zero-phase current transformer in combination with a low-voltage model. (compatible)
- The filter circuit has been strengthened, so it can operate normally even with current with a distorted waveform. It is also resistant to radio wave interference, noise, and surges.
■Structure
The LSG-6TB/10TB series has a built-in case made of steel plate, and the front cover is also made of steel plate. The power supply is fixed to the case, and the unit is plug-in type. Space unit U-23 is available for unused circuits.
■Operation
If a leakage occurs in the load side circuit after the zero-phase current transformer is installed, an electromotive force will be generated at the secondary terminal of the zero-phase current transformer. After adjusting the sensitivity of this secondary output, the amplifier circuit amplifies it, the level detection circuit determines its magnitude, the switching circuit operates the output contact, and the operation indicator light lights up at the same time.
When the earth leakage is eliminated, the earth leakage operation indicator light turns off and the output contact returns, but the earth leakage operation indicator lamp continues to indicate that there was an operation. However, if the control power is lost, the light will turn off. The earth leakage indicator light turns off when the test/reset switch is moved to the reset side.
■Features
・Protects low-voltage circuit equipment from electrical leakage.
・It has functions of displaying whether it is in operation or whether it is in operation.
・Up to 6 circuits can be detected. Please use space unit U-23 for unused circuits.
・It is a harmonic countermeasure product.
・Compliant with "JIS C 8374 Earth Leakage Relay".
