This liquid-cooled CCS2 handle delivers 500 A continuous at up to 1000 V DC and stays cool during long sessions, helping contacts and cable last longer. It is weather-resistant for outdoor sites (IP55), quiet at the handle (under 60 dB—about normal conversation), and works from −35 °C to +50 °C. The grip is designed for easy daily use, so drivers can plug in and pull out without strain, and the mechanism is tested for more than 10,000 cycles.
Integration is straightforward. Plan a cooling flow of 1.5–3.0 L/min and a working pressure of 3.5–8 bar; a 5 m cable typically holds about 2.5 L of non-conductive silicone oil. Heat removal scales with load (about 170 W at 300 A, 255 W at 400 A, 374 W at 500 A), while typical system power remains low. Durable housings (PC and PA66-GF) and silver-plated copper contacts support long service life. Ask for the datasheet to see thermal curves, wiring notes, and certification details.

What continuous current can I plan for?
This handle is engineered for 500 A continuous at up to 1000 V DC with a temperature rise < 50 °C when the cooling loop meets spec. Ask us for the thermal curves to match your ambient and duty cycle.
What cooling loop do I need?
Use a silicone-oil circuit sized for 1.5–3.0 L/min flow at about 3.5–8 bar to the handle. A 5 m cable typically holds ~2.5 L of coolant; typical per-handle power is <160 W. We provide integration notes for pumps, heat exchangers, hoses, and quick-connects.
Is it suitable for outdoor public sites?
Yes—outdoor rated with IP55 sealing and an operating range of −35 °C to +50 °C. Handle acoustics are <60 dB (about normal conversation), and mating force is <100 N for easy daily use. The mechanism is tested for >10,000 cycles.
Will it work with my CCS2 charger and standards?
The design complies with IEC 62196-3 requirements for DC high-power couplers and supports temperature sensing at critical zones. It is intended for CCS2 EVSE systems; wiring maps and sensor signal details are included in our integration guide. TÜV/CE documentation is available on request.
What maintenance is required?
Keep the coupler face clean, inspect seals and latch components on schedule, and check coolant level/filters during routine service. Avoid high-pressure jets directly on the face. A maintenance checklist and service intervals are provided in the service guide; warranty is 24 months.
Which options and customizations are available?
Current classes from 300–500 A, matched liquid-cooled cable assemblies, and common cable lengths are available. We also offer ODM/OEM options (branding, grips, accessories like holsters and protective caps). Samples and lead times can be confirmed with our engineering team.
