The EATON MSH1-3A is a thermal unit designed to replace damaged or worn thermal units in overload relays. These thermal overloads prompt contactors to break electrical connections with downstream equipment once a set temperature is reached to protect connected loads from overheating and causing damage.
The EATON MSH1-3A thermal unit is a required component of thermal-type overload relays and should be selected based on the appropriate operating conditions of the motor starter.
