EMD Fan Control – Honeywell’s Fan Control thermal switches are specifically designed and qualified to operate the cooling fan contactor on EMD locomotive engines. This thermal switch is non-adjustable, thermally stable and is provided in a continuous range of temperature setpoints shown in the table below.
It uses large rugged contacts, high armature force and large snap-acting discs. This enables the fan control thermal switch to meet rugged performance requirements.
The base sensing module of the switch is a hermetically sealed element ensuring long life through a large range of environments.
