The nVent RAYCHEM JBS-100-ECW-A is an electronic temperature controller that provides accurate control for all heating cables. Housed in a NEMA 4X enclosure and designed to be wall mounted the unit includes a window and a digital display that shows the monitored actual/set point temperatures and alarm conditions (RTD failure, high or low temperature) if detected. Alarm conditions can be remotely indicated via a Form C dry contact. Status LEDs indicate whether the digital display is showing the set point or actual temperature. Programming the set point temperature, dead band, and high and low alarm thresholds on the JBS-100-ECW-A are accomplished using the built in digital display and push buttons.

The JBS-100-ECW-A is programmable to maintain temperatures of 425°F, can be used with voltages from 100 to 277 Vac, and is capable of switching current up to 30 Amps. Temperature data is provided by customer supplied 100-ohm platinum RTD, which can provide feedback for either temperature maintenance or ambient sensing for freeze protection. The kit contains all the necessary materials for a complete installation. For a direct connection to a nVent PYROTENAX Mineral Insulated cable, eliminating the need for a field power connection device, a grounding kit is required (ordered separately).
