Earth leakage relay LEG-130L series
Hikari Shoko Co., Ltd.
About This Product
Detects electrical leakage in low voltage AC circuits.
■Features
- Compliant with JIS C 8374.
- Compact and easy to install, does not take up installation space.
・It is a harmonic countermeasure product that is not easily affected by noise such as radio waves and surges.
- Can be used with control power supply AC100V and AC200V. (Terminal connection switching type)
・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 switching circuit lights up the LEAK (operation indicator light) and operates the output contact at the same time.
After operation, for LEG-130L (manual return method), the LEAK (operation indicator light) will not go out and the output contact will not return until the RESET (reset) switch is pressed. With LEG-130LA (automatic return method), when the leakage is eliminated, the LEAK (operation indicator light) turns off and the output contact returns at the same time.
■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".
