nVent RAYCHEM SBS-xx-MV-20 Control Panel for surface snow melting systems

Overview

Multi-Circuit control panel

The SBS-XX-MV-20 control panel for surface snow melting systems provides a totally integrated electrical safety, connection and control solution for RAYCHEM EM2-MI Mineral Insulated heating for surface snow melting applications. The control panel comprises the VIA-DU-20 multi-sensor control unit for energy efficient ground surface heating, and integrated electrical safety devices.

The SBS-xx-MV-20 panels offer solutions up to 18 maximum circuits of EM2-MI. 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 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.
The panels need only be connected to the 400Vac (3 phase) supply.
