Siemens Industrial Controls SMFH42 1-Pole Heater Element 6.80-7.57A

The Siemens Industrial Controls SMFH42 Thermal Overload Heater Element is designed for use in motor starter assemblies and industrial HVAC systems requiring overload protection. Rated for 6.80 to 7.57A at 600 VAC, this Class SMF heater element assists in protecting electric motors from overheating caused by excessive current or stalled operating conditions. It is commonly placed in motor control panels, air handling units, pumps, compressors, and ventilation equipment used in commercial facilities and industrial conditions. Within the control circuit, the heater element works with compatible overload relays to interrupt motor operation when unsafe current levels are detected, assisting routine equipment protection and system accurately.
