The CKJ11-3000 is a low-voltage vacuum contactor designed for high-current switching in renewable energy and heavy industrial applications. It features a rated current capacity of 3000A, making it the highest-capacity vacuum contactor in its class according to the supplier's testing data. The unit operates at AC-1 and AC-3 load categories, with a rated insulation voltage of 1140V and a rated working voltage of 690V. It has been subjected to electric performance, ambient, and shock-vibration tests as per IEC 60947-4-1 standards.
The contactor uses a vacuum interrupter chamber with silver-tungsten alloy contacts, typical for industrial vacuum contactors requiring high arc resistance and long service life. Its coil voltage options include 24V DC, 110V AC, and 220V AC, compatible with standard control circuits. The housing is constructed from flame-retardant polycarbonate, meeting UL94 V-0 requirements. No certifications are claimed beyond internal test validation, and no third-party certification marks are referenced in the source material.
This contactor is primarily used in solar inverters, wind turbine pitch systems, large smelting furnaces, and railway traction equipment where frequent switching under high inrush current is required. Buyers typically source it for integration into custom control panels or as a replacement in legacy systems. Packaging is standard industrial carton with foam inserts. Trade terms are FOB Shanghai, with lead time and MOQ to be confirmed directly with the supplier. No minimum order quantity is stated in the listing.

Kunshan Guoli Electronic Technology Co. Ltd. is based in Kunshan, Jiangsu Province, China, with a registered address at St 28 Xihu Road. The company is registered as a manufacturer of electronic control components, and the listing shows it developed the CKJ11-3000 vacuum contactor independently. There is no public information on years in operation, employee count, or revenue. The supplier has no verified response rate or response time recorded, and no certifications are claimed beyond internal prototype testing.
The company's profile does not list any export history, client names, or third-party quality audits. It is classified as a harbor-tier supplier, indicating basic platform verification only. The product description suggests engineering capability in vacuum interrupter design, but no evidence of ISO, CE, or CB certification is provided. Buyers should treat this as a direct-from-factory source with no third-party quality assurance claims documented in the listing.

Sourcing CKJ11 Series CKJ11-3000 from Kunshan Guoli Electronic Technology Co. Ltd. - China Import Guide
Before ordering, verify the contactor's coil voltage compatibility with your control system, confirm the contact material composition, and request documentation of internal test results for shock, vibration, and ambient conditions. Since no third-party certifications are claimed, ensure your quality assurance team reviews the supplier's test data or performs incoming inspection for insulation resistance and contact resistance under load. Do not assume CE or IEC compliance without explicit evidence.
Lead time and MOQ are not stated in the listing and must be confirmed directly. The supplier is based in Kunshan, near Shanghai Port, so FOB Shanghai is the likely incoterm. Packaging is standard industrial carton with foam, but buyers should specify if export-grade moisture protection or wooden crate reinforcement is required. Payment terms are not disclosed; common options include 30% advance with 70% against B/L copy, but this must be negotiated.
For quality verification, request a sample for contact resistance measurement using a micro-ohmmeter and perform a dielectric withstand test at 1500V AC for one minute. Inspect the vacuum interrupter for visible cracks or discoloration. Confirm the presence of any auxiliary contacts and their ratings. Ask for a batch traceability code and a test report for each shipment. Document all findings before release for shipment.
