Two-stage alarm earth leakage relay LEG-300L
Hikari Shoko Co., Ltd.
About This Product
■Reliable earth leakage monitoring with two-stage alarm and measurement display
・Compliant with JIS C 8374 earth leakage relay.
- Detects earth leakage in low voltage AC circuits in combination with low voltage ZCT.
・Protects in two stages: light leakage and heavy leakage.
- Sensitivity current and operating time can be set separately for light leakage and heavy leakage.
・Digital display of current value and maximum value of zero-sequence current.
- You can enable/disable the harmonic filter.
- Self-diagnosis function automatically detects internal circuit abnormalities.
■Function
・Two-stage alarm
Light leakage and heavy earth leakage can be operated separately, allowing two-step protection such as issuing a preventive alarm for light leakage and shutting off for heavy earth leakage.
・Sensitivity current
Light leakage can be set in 0.1A increments in the range of 0.2 to 1A, and heavy earth leakage can be set in 1A increments in the range of 2 to 10A. The sensitivity current can be switched finely, making it easier to adjust the control value.
・Operating time
Light leakage and heavy earth leakage can be set at 0.1, 0.3, and 0.5 to 1.0 seconds (every 0.5 to 0.1 seconds). The operating time can be changed in detail, making it easier to adjust the management values.
・Measurement display
The current value and maximum value of zero-sequence current can be displayed, and the status can be checked numerically.
・Harmonic countermeasures
A harmonic filter cuts harmonic components. It can be enabled/disabled as needed, and it is also possible to detect earth leakage including harmonics.
・Self-diagnosis function
Internal circuits are automatically tested periodically and equipment abnormalities can be detected at an early stage. Self-diagnosis can be enabled/disabled by setting.
■Features
・Protects low-voltage circuit equipment from electrical leakage.
・Two-stage alarm type for light leakage and heavy earth leakage.
・The two-stage alarm earth leakage relay is a product that can be operated without shutting off in low-voltage equipment where earth leakage current is constantly flowing.
- Equipped with a digital display to display measured values.
- Automatic/manual return switching method.
・It is a harmonic countermeasure product. (You can switch the harmonic filter ON/OFF.)
・Compliant with "JIS C 8374 Earth Leakage Relay".
