nVent RAYCHEM SBS-XX-CX Control Panels for surface snow melting systems

Overview

SBS-XX-CM-20 and SBS-XX-CW-40 Multi-Circuit control panels

The SBS-XX-CM-20 control panel for ice and snow prevention systems provides a totally integrated electrical safety, connection and control solution for RAYCHEM EM2-CM constant wattage heating mats for surface snow melting applications. The panels offer solutions up to 18 maximum circuits of EM2-CM mats.
The panels need only be connected to the 230Vac supply.

The SBS-XX-CW-40 control panel for ice and snow prevention systems provides a totally integrated electrical safety, connection and control solution for RAYCHEM EM4-CW constant wattage heating cables for surface snow melting applications. The panels offer solutions up to 18 maximum circuits of EM4-CW cables.
The panels need only be connected to the 400Vac (3 phase) supply.

The control panel comprises the VIA-DU-20 multi-sensor control unit for energy efficient ground surface heating, and integrated electrical safety devices. The panel also includes electrical circuit protection devices (C-type circuit breakers) and residual current devices for safety and peace of mind.

Key benefits:
  • Fast connection of multiple circuits directly into the control panel
  • 3-18 circuit lengths can be connected and switched by a single panel.
  • Circuit protection and safety devices integrated into the panel.
  • Complete system from the manufacturer. System and components specifically selected for high performance ice and snow prevention system control.
