This standard adopts IEC947-4-1 (1990) "Low-voltage switchgear and control equipment Part 4 Contactor and motor starter".
1 Subject content and scope of application
This standard specifies the common types, parameters, technical requirements, test methods and inspection rules of CJX series AC contactors. This standard applies to CJX series AC contactors (hereinafter referred to as contactors). The contactor is mainly used in circuits with AC 50Hz (or 60Hz), rated working voltage up to 660V, and rated working current up to 170A when the rated working voltage is 380V under AC-3 use category, for remote connection and disconnection of circuits, and can be combined with appropriate thermal overload relays to form electromagnetic starters to protect circuits that may be overloaded.
1.1 This standard applies to the following basic varieties and specifications of AC contactors: a.
CJX1 series AC contactors;
CJX2 series AC contactors;
CJX3 series AC contactors;
CJX4 series AC contactors;
CJX5 series AC contactors
Other varieties and specifications of the above series can be formulated by the manufacturer to meet the general requirements of this standard. Enterprise standards. 1.2 The basic requirements for the combination of contactor and functional module (functional electrical appliance) and interlocking contactor composed of two contactors are proposed in the form of supplementary parts, which are used together with this standard. 2
