Omega FGT Data Sheet

FGT Series

Bi-Metal Inline Thermostat

• Bi-metal Thermostat for all heating elements up to
15 Amp depending on their operating voltage e.g.
Cirrus Fan Heaters, Nimbus Convection Heaters,

PTC Heating Proles, etc.

• Can be operated in a voltage range of 12 Vac/dc
to 24Vac/dc or 100 Vac to 230 Vac

• Reliable bi-metal technology

• Normally closed contact (heating)

• Pre-set switching temperature

• Self-assembly component

Applications

• Interior heating for electric / hybrid vehicles and
special-purpose vehicles, e.g., electric buses,
commercial vehicles, cranes, excavators, etc.
