The Workersbee CCS1 400A DC charging connector is designed for DC charging systems that require a naturally cooled high-current connector. It follows the SAE J1772 interface standard and is intended for electric vehicles using the CCS1 charging interface.

The connector is rated at 400A and 1000V DC. Key parameters include insulation resistance above 500MΩ, withstand voltage of 3000V, insertion and withdrawal force below 100N, and a mechanical life above 20,000 no-load cycles. The flammability rating is UL94 V-0.
For outdoor and commercial charging environments, the connector is specified to IP55 and supports an operating ambient temperature range from -40℃ to 50℃. The product also supports temperature monitoring, which must be enabled in use according to the specification.
The 400A version supports project-based customization of cable length, stripping length, lug type, and sensor type. Available sensor options include PT1000 and NTC, depending on charger-side integration requirements.

Is this connector suitable for CCS1 DC charging applications in North America?
Yes. It is designed for CCS1 DC charging applications in North America. Final compatibility should be confirmed with the charger configuration and target vehicle range.
Is CCS1 the same as J1772?
No. J1772 is mainly used for AC charging, while CCS1 is used for DC fast charging.
Does a 400A CCS1 connector always require liquid cooling?
No. This product uses a naturally cooled cable structure. Cooling requirements depend on the charger design and operating conditions.
Why is temperature monitoring important?
It helps control heat at high-current contact points during DC charging and supports thermal management.
What can be customized for this connector?
Cable length, stripping length, lug type, and sensor type can be customized.
What should buyers confirm before deployment?
Buyers should confirm vehicle inlet compatibility, charger electrical ratings, thermal strategy, certification path, and operating conditions.
