Raychem JBS-100-ECP-A Junction Box Controller

Raychem JBS-100-ECP-A is a pipe-mounted power connection box with an integrated digital electronic controller for Raychem heating cables, combining the junction box, power terminations, and control electronics in a single NEMA 4X enclosure. It is designed to work with Raychem polymeric self-regulating cables and Pyrotenax mineral-insulated (MI) cables, providing local control of a heating circuit and a convenient field connection point for heat-tracing installations on piping. This kit ships with the enclosure and electronics plus installation accessories, including a lid, wire cover, a box with electronics, a green/yellow grounding tube, core sealer for MI cables, a battery connector, a stand with RTDH, cable lubricant, cable ties, an MI grounding kit, and a plug. The unit is intended for 100–277 VAC input (some listings specify 100/277 VAC), delivering reliable power to the connected heat-tracing cable and enabling on-site control via the built-in electronic controller. Its rugged, weatherproof housing is designed for environments where moisture and dust exposure are a concern, ensuring safe operation in typical industrial pipe heating applications. In the Raychem family, the JBS-100-ECP-A is a combination power connection box and electronic controller, with mounting hardware and end seals sold separately as part of the broader kit ecosystem.
