Tpi DCSMT303 Disconnect Switch Electric Unit Heater

Product Description

The TPI DCSMT303 is a disconnect switch designed for use with commercial suspended electric unit heaters. A disconnect switch provides a dedicated means to isolate electrical power to a heating unit, allowing safe servicing, maintenance, and code-compliant shutoff without returning to the main panel. This component is installed by licensed electricians or HVAC technicians working on commercial heating systems. It mounts in line with the heater's power supply circuit and is rated for the high-current demands typical of electric resistance unit heaters found in commercial and industrial spaces.

This disconnect switch is intended for commercial suspended heating applications, specifically designed for use with TPI Corporation Multi Watt Electric Unit Heaters. It is commonly installed in warehouses, garages, workshops, loading docks, and other commercial or light-industrial spaces where suspended electric unit heaters provide primary or supplemental heat. The disconnect provides a local lockout point required by electrical codes for serviceable equipment.
