Protective design: CJX2 3P 25A AC Contactor adopts protective structure, which is characterized by small volume, light weight, low power consumption and long life.
Direct-acting action structure: Its action structure is direct-acting and the contacts are double-breakpoint, which improves the reliability and safety of contact.
Block-type auxiliary contact group: auxiliary contact group, air delay head, mechanical interlocking mechanism and other components can be added according to the user's needs to form a time-delay contactor, reversible contactor, star-delta starter and other derived series products.
The main technical parameters of CJX2(ST1N) series AC contactor include:
Rated voltage: including 36V, 110V, 127V, 220V, 380V and other levels to meet the needs of different power systems.
Rated current: According to different models, the rated current ranges from 9A to 95A.
Coil voltage: AC coil voltage includes 24V, 36V, 48V, 110V, 220V, 380V, etc. DC coil voltage includes 12V, 24V, 48V, 110V, 220V, etc.
Mechanical and electrical life: Mechanical life can be up to millions of times, and the electrical life is also relatively high, which ensures the long-term stable operation of the contactor.
Installation: CJX2 Type AC Contactors can be mounted with two screws or 35mm (or 75mm) guide rail, which is convenient and quick. The relevant technical data should be checked before installation to ensure compliance with the installation conditions.
Maintenance: All parts of the product should be checked regularly during use, requiring that movable parts are not stuck and fasteners are not loose. If there is any damage, it should be replaced in time to ensure the normal operation of the contactor.
