CJ20-40 AC Contactor 55A 3 Poles Electrical Magnetic Contactor Three Phase
Product Description:
CJ20 Series AC Contactors (hereinafter referred to as "contactors") are primarily used in AC circuits at 50 Hz (or 60 Hz), with a rated operating voltage up to 660 V and a rated operating current up to 630 A. They are designed for remote switching and disconnection of circuits and can be combined with appropriate thermal overload relays to protect circuits that may experience operational overload. Meet the standards: GB / T14048.4, IEC / EN 60947-4-1.
Product Feature:
The contact system of the CJ20 series contactors is a direct-acting, double-break arrangement. For models CJ20-40A and above, the auxiliary contacts are installed as independent components on both sides of the main contacts, and they are electrically separate.The CJ20-10 to CJ20-25A products can be installed either with screws or on a standard 35 mm DIN rail.The CJ20-10 to CJ20-16A products uses a double-break simple open and close arc chute. For the rest of the range (CJ20-63 to CJ20-630A), a grid-type arc hood is used, which offers the advantages of high breaking capacity and high reliability.The CJ20-63 to CJ20-630A energy-saving models feature an AC/DC universal energy-saving module. This module not only enables the production of noise-reducing and energy-saving variants or DC-operated versions but also does not occupy auxiliary contact space, significantly improving the reliability and lifespan of the product.
