Detailed Product Description
JDA Series Thermal Relay
JDA series electrical thermal relay introduce integrated circuit and technology from the USA Westing house company. As the new replaced product, it is suitable for AC motor with AC 50Hz, voltage up to 660V. It is used for phase breaking and overload protection. It has wide current adjustable range, light emitting diode indication, good visibility, high sensitivity and reliable operation. It will not be impacted by ambient temperature. It can be installed in free angle.
