Product details

nVent RAYCHEM EM4-CW constant power output heating cable assembly for fast and effective ramp and access way heating, to prevent ice and snow formation.  The pre-terminated EM4-CW cable assembly comes complete with a end seal and a 4 metre cold lead eliminating the need for onsite termination. Easy to use simply install the cable assembly over the required area and connect the cold lead to a junction box and RAYCHEM control device or SBS-XX-CW-20 control panel. The EM4-CW assembly is an ideal solution for track heating of ramps, loading bays, driveways, emergency escapes routes and pedestrian walkways, where a 3 phase 400 V supply is available.
