Little Giant MTK-32-3-1 Differential thermal Overload 0.63-1A Class 10

The Little Giant MTK-32-3-1 Differential Thermal Overload is a protective electrical component used in HVAC systems and related pumping equipment to safeguard motors operating within 0.631A range. It is commonly applied in condensate removal pumps, circulation units, and auxiliary HVAC water systems where controlled motor protection is required. The system responds to temperature and current variations disconnecting power during abnormal operating conditions to prevent motor and circuit damage. It is installed within the motor control assembly and works in coordination with start and run circuits to maintain stable electrical operation during routine system cycles in commercial conditions.
