NXCC series contactors for capacitor switching (hereinsafter referred to
as contactor) is mainly used in power systems with AC 50Hz or 60Hz,
rated operating voltage up to 690V. It is used to connect and disconnect
shunt capacitors with the aim to improve power factor.

The limiting working temperature is -35℃~+70℃,the normal working temperature is -5℃
~+40℃,and the average temperature within 24 hours is not more than +35℃.If it is not in the
normal operating temperature range,the capacity reduction shall be considered.
Relative humidity should not exceed 50% at temperature up to +70℃, higher relative humidity is
allowed under lower temperature, for example up to 90% at +20℃. User should take special
measures against condensation due to temperature change.
The applicable temperature range for transportation and storage conditions is between -25℃ and
+55℃, which can reach +70℃within a short-time (24h). The storage place shall be ventilated and
dry, and shall not be attacked by rain, snow and shall not be exposed to direct sunlight.
