JRS4 Series Thermal Overload Relays apply to the AC circuit with 50/60Hz frequency,and 660V rated voltage,provide thermal overload and phase failure protection.Combined with CJX2 series Ac contactors, they can use as an electromagnetic starter to protect the circuit which may be overloaded. They can meet the requirements of GB14048.5 and IEC60947-5-1 standard
