description


1.Application

JR30 series thermal relay is used in the circuit of 50/60Hz, rated insulation voltage 660V,rated current 0.1-85A for protecting the phase break when the electric motor is overloaded. Therelay has different mechanism and temperature compensation. It can be plugged in CJX5 seriesAC contactor. The product conforms to IEC60947-4-1.
