The RT-SP junction box is intended for connecting and branching intrinsically safe signal, measuring and power supply circuits in explosive atmospheres of groups I and II. The construction of the box depends on its use and differs in the size of the housing, the number of glands and the number and type of connection connectors as well as the number of internal connecting elements. If only glands in the form of glands are used, we have any option of configuring internal connections by the user. When using bushings in the form of connectors, the configuration is limited by the number of contacts in the connector and the way of wiring (in CONINVERS connectors, wires are soldered and in AMPHENOL connectors). You can also use versions that have all types of bushings both glands and connectors. Connector type bushings are usually used for dedicated purposes for a specific project or for connecting equally wired external devices
