Image of EM4-CW Cable

EM4-CW is a constant output heating cable for simple, fast, and effective ramp and accessway heating to prevent snow and ice formation.

The pre-terminated EM4-CW cable comes complete with a 4m cold lead, removing the need for on-site termination activities. Simply install the heater over the required area and connect the cold lead to the power junction box and “Smart” control unit.

The EM4-CW heating cable is designed for applications where a 3 phase (400V) supply is available.
