Overview

AJBXR series junction box is suitable for integrating less than two obstruction lights’ power wires and/or alarm wires.

AJBXR junction box is composed of an aluminum compartment with terminal blocks, 2-4 units of threaded hubs (common G3/4’’ or G1/2’’ or G1’’)and watertight cable glands. AJBXR’s aluminum compartment contains a screw-type terminal block with four non-fused poles and one grounding pole.

With 2/3/4 threaded hubs, there are three sub-models for connecting obstruction lights’ wires.

AJB2R

  • Integrating one obstruction lights’ power and/or alarm wires

AJB3R

  • Integrating two obstruction lights’ power and/or alarm wires
  • Integrating a PHC01 photocell’s power and loads

AJB4R

  • Integrating three obstruction lights’ power and/or alarm wires (for conduit installation structure)

•              Integrating a PHC01 photocell’s power and loads (for conduit installation)

Features

  • Ideal solutions for connecting 1-2 obstruction lights
  • Aluminum alloy enclosure epoxy coated provides good weather and corrosion resistance
  • Universal G3/4’’ / G1/2’’ / G1’’ conduits
  • Nickel-plated brass cable glands with G3/4’’ / G1/2’’ / G1’’ joint and silicon gasket provide robust waterproof protection
  • With built-in screw-type terminal block for easy wiring
  • With internal and external earthing studs for grounding connection
