Product Details
Thermal Overload Relays
Schneider Electrics K thermal overload relays are adjustable from 0.11 to 11.5 A, they have been predominantly designed for use in applications that require motor protection.
This range of mini thermal overload relays feature compensated and phase failure sensitivity, the range also offers manual and automatic reset. Each overload relay has 3-poles and screw clamp terminals.

Applications of a Contactor and Control Overload Relay
The majority of the time is to protect a motor
To detect both overload conditions and fault conditions to then announce trip command for a protective device
To deactivate a device whenever it pulls high current
Sometimes developed into microprocessor systems and solid-state electronics
