从China供应商批发进口Ac Contactor Chv-400/3.3 — FOB条款

The AC Contactor CHV-400/3.3 is engineered for AC electrical systems operating at 50Hz, with a rated voltage of up to 3.3kV and a current rating of 400A. It is designed to make or break circuits reliably, making it suitable for controlling AC motors in applications requiring frequent start-stop cycles. The contactor’s construction supports high-duty industrial environments, including power systems, oil fields, chemical plants, mining operations, metallurgical facilities, and electrified railways.

Built to standard industrial specifications for medium-voltage contactors, the CHV-400/3.3 typically incorporates silver or silver-alloy contacts for high conductivity and arc resistance, with a standard mechanical endurance of 1 to 3 million operations. The contactor usually features a coil voltage compatible with 50Hz systems, and its enclosure is often rated to IP20 or higher for protection against solid foreign objects. Typical dimensions for this class of contactor range from 150mm to 300mm in length, depending on the pole configuration and auxiliary contacts.

This model is primarily used in industrial automation and motor control panels, where it manages the switching of high-power loads. Buyers typically include electrical panel builders, OEMs for industrial machinery, and maintenance teams in heavy industries. Trade terms for such contactors often involve bulk packaging in cartons, with MOQs and lead times confirmed directly with the supplier. The product is well-suited for environments where electrical reliability and durability under repetitive switching are critical.

Kunshan Guoli Electronic Technology Co. Ltd. is based in Kunshan, Jiangsu Province, China, with its registered address at St 28 Xihu Road. The company specializes in the production of electrical components, including AC contactors designed for industrial and heavy-duty applications. Its product range targets sectors such as power systems, oil fields, and metallurgy, where reliable switching and motor control are essential.

The supplier operates within the harbor trust tier, indicating a verified presence in the marketplace. While the response rate and average response time are currently not available, the company’s focus on medium-voltage contactors suggests a niche expertise in high-current electrical control devices. The profile does not provide details on certifications, production capacity, or client base, which buyers are advised to confirm directly.
