Features

• Compact thermoplastic case sealed to prevent ingress of dust and moisture.
• Easy to install, convenient clip-tray mounting.
• 50 mm dia. for conductor access.
• Remote cores (70, 105, 152, 190 mm dia.) available for larger conductors, or for remote sensing.
• Earth leakage test button to verify that the power supply, sensing and detecting circuits as well as the MCCB tripping mechanism is in working order.
• Remote tripping facility available on request.
• Highly stable on long cables and on starting motors.
• EL306 maintains sensitivity over a wide range of voltage (110 – 550 Vac) and temperature -5 °C to +60 °C
• Immune to the effects of pulsing DC.
• High immunity to nuisance tripping due to high voltage surges, e.g. lighting.

Applications

• Used in heavy industrial and mining applications to detect leakage currents. It is compact, and has a test button to verify the power supply, sensing and detecting circuits as well as the MCCB tripping mechanism is functional.
