Earth leakage relay LEG-107L series
Hikari Shoko Co., Ltd.
About This Product
Detects electrical leakage in low voltage AC circuits.
■Features
- Compliant with JIS C 8374.
・It is a harmonic countermeasure product that is not easily affected by noise such as radio waves and surges.
・Compatible with all low-voltage zero-phase current transformers.
・This is an environmentally friendly product (compliant with the European RoHS Directive).
■Operation
In combination with a zero-phase current transformer, it provides earth leakage protection for low-voltage distribution lines. If a leakage occurs in the load side circuit after the zero-phase current transformer, an electromotive force will be generated at the secondary terminal of the zero-phase current transformer. After this secondary output is amplified by the amplifier circuit and its magnitude is determined by the level detection circuit, the output contact is activated by the switching circuit, and the operation indicator lamp lights up at the same time.
After operation, the automatic return method returns the output contact and turns off the operation indicator when the leakage is eliminated. With the manual reset method, the output contact will not reset and the operation indicator will not turn off until the reset switch is pressed.
■Features
-Exposed type earth leakage relay.
・Protects low-voltage circuit equipment from electrical leakage.
・It is a harmonic countermeasure product.
- Compliant with "JIS C 8374 Earth Leakage Relay".
