Lighting Junction Box LJB2

Austdac Intrinsically Safe Lighting Junction Box LJB2

About


The intrinsically safe junction box type LJB2 is part of the Austdac area lighting system type LLS1 that is designed to provide plant and area illumination in underground coal mines. The LJB1 finds application on longwalls, around load centres and on machinery such as road headers, continuous miners and roof bolters for general area illumination.

The LJB2 junction box provides a convenient method of connecting LED luminaires type SS11-6L to a single power supply such as the Austdac AC36W. The LJB2 is designed for a daisy chain installation.

The junction box is provided with up to three two-pin input connector for connection to the power source and one six-pin connector for connection to luminaires type SS11-6L. The use of connectors in the LED lighting system allows for convenient fast installation and tear down during longwall moves.

The lighting junction box type LBJ2 is certified intrinsically safe as either Ex ib I Mb for power systems that are shut down in mine ‘gassed out’ situations or Ex ia I Ma for situations where area lighting is required during mine ‘gassed out’ situations such as self rescuer caches. The perfect power source would then be the Austdac uninterruptable power supply type 12/NMH/288.

The junction box and connectors are ingress protected to IP56 allowing the system to be washed down when required.
