Catalog excerpts

1.APPLICATION RANGE CJX2 series AC Contactor is mainly used in the circuit of AC 50Hz or 60Hz, rated operating voltage up to 690V, rated operating current up to 630A, for the use of remotely connecting and breaking, it also can be connected with thermal relay combined into electromagnetic starter to protect the circuit’s over-load of operation. Product confirms to: GB14048.4, IEC60947-4-1 etc. standards. 2.Model and its implication CJ X 2 Number of pole (2 or 4, it implies as 3P when does not note) Derived code, it implies as directional contactor if with N (Ns is the horizontal installation, Nc is vertical installation) Rated operating current (when AC-3, 380V) (A) Design serial No. Miniature AC Contactor 3.APPLICATION ENVIRONMENT CONDITION 3.1 Altitude height of Installation places does not exceed 2000m 3.2 Ambient temperature Up limitation of ambient temperature does not exceed +40℃; Average value in 24h of ambient temperature does not exceed +35℃. The low limitation of ambient temperature does not lower than -5℃. 3.3 Condition of atmosphere 3.3.1 Humidity When it is the highest temperature +40℃, the relative humidity does not exceed 50%, and it allows a certain high relative humidity when it is at relatively low temperature. For example, it reaches 90% when 20 ℃ , and it should take special measurements when there occurring condensation due to the temperature variation. 3.3.2 Pollution grade:3 3.4 Installation condition Installing at the places that without impact vibration and without snow or rain; up terminal connects power, and the low terminal connects the load; the gradient between the vertical and the product does not exceed 5° 3.5 Installation category: III
