Description
The Viking DUMRS20 Thermal Switch is a replacement thermal switch with a 20A rating, designed to interrupt current as temperatures rise to protect electrical components in gate operator and access control systems.
In practical applications, it serves as a protective element within control panels, drive circuits, or power interfaces, tripping when overheating is detected to prevent damage to motors, relays, and wiring during high-cycle operation. This part is intended for use as a replacement when the original thermal switch has failed or degraded, aligning with standard servicing practices for perimeter security equipment.
Compatibility: Specific operator models, mounting styles, voltage levels, and system compatibility are not listed in the provided data. This description covers generic use as a 20A thermal-switch replacement; verify fit, mounting, and electrical connection against your equipment’s documentation before use.
