Schneider C400/A8/1/1/1/00 is a dedicated AC contactor belonging to Schneider Electric’s Acti 9 product series, primarily designed for on/off control of medium and low-power AC loads (such as small motors, electric heaters, and lighting systems) in industrial control circuits, 

commercial power distribution systems, and residential electrical equipment. Its model coding “C400/A8/1/1/1/00” specifies key functional configurations: it features a rated control voltage matching standard AC power systems, 

1 normally open (NO) main contact for main circuit control, 1 normally open (NO) auxiliary contact and 1 normally closed (NC) auxiliary contact for auxiliary circuit signaling or interlocking, 

and a basic protection-free design (denoted by “00”) to adapt to scenarios requiring external protection devices.

The contactor adopts high-conductivity copper alloy contacts and an optimized electromagnetic drive system,

 ensuring low contact resistance during operation (reducing energy loss) and reliable switching performance—capable of withstanding inrush currents when loads start, avoiding contact welding or damage. 

It complies with international electrical standards such as IEC 60947-4-1, with a flame-retardant housing that meets V0 fire resistance grade, enhancing safety in case of electrical faults.

In terms of installation and compatibility, Schneider C400/A8/1/1/1/00 supports standard DIN rail mounting, enabling quick integration into Acti 9 series distribution cabinets or control panels; its compact size saves installation space, 

making it suitable for dense wiring environments. Additionally,

 it maintains stable operation across a wide temperature range (-25°C to +60°C) and has strong anti-electromagnetic interference capabilities, adapting to diverse industrial and commercial operating conditions, thus ensuring long-term reliable control of AC loads.
