RT12M General Electric RT1 Thermal Overload Relay, 5.5-8.5A
RT12M identifies the General Electric Class 20 thermal overload relay with a 5.5-8.5 A adjustable setting. The unit belongs to the RT1 direct-mount family and provides overload protection when paired with the contactors named in the GE selection chart.
Ordering by the complete number matters because RT1M is a Class 10 model and RT12L or RT12N cover different current ranges. Match RT12M to the equipment record and confirm the motor setting before installation.
