GRB Series PTC Temperature control module
1.SUMMARIZATION
The GRB series PTC Temperature control module is specially designed for
being used with MZ6 PTC Thermistors, if the electric motor ( or some place on the
electric motor)is overheating, the resistance of PTC Thermistors will rise, and can be
passed to the protection apparatus, the relay contact inside the protection apparatus
transforms to push the control circuit(electromagnetic switch etc) to switch off the
main power source, and further to protect the elector motor.
