Built for heavy-turnover public DC sites, this GB/T 20234.3 plug delivers stable fast charging up to 1000 V and 80–300 A (air-cooled). The impact-resistant housing and sealed interface are rated IP55 when mated. The profile guides a positive click-in, and the strain-relief protects the cable during repeated cycles. Silver-plated contacts and a low-impedance path help limit temperature rise under load. A motorized lock with a mechanical emergency release enables safe interruption when required. The assembly is qualified for −30 °C to +50 °C operation and 10,000+ mating cycles.
For operators, the value is predictable service and easy upkeep. The handle seats cleanly in rain or dust, sustains the set current, and releases smoothly when billing completes. Field technicians get clear labeling and access to common wear parts (seals, latch components, microswitch) to speed replacement. Tail-end terminations follow standard practices, supporting common cable sizes for straightforward retrofit. Compatible with mainstream GB/T dispensers, it fits highway hubs, fleet depots, and retail car parks where fast turnarounds and low downtime matter.
The GBT EV Plug is compliant with the GB/T20234.2-2015 standards for EV Plugs & Sockets. The standard defines the requirements for the design, construction, performance, and testing of EV plugs, sockets, and adapters.

WORKERSBEE EV Plugs are manufactured with accuracy and efficiency by fully automatic production lines. The 360-degree visual inspections are carried out at each stage of the production. Attention to detail is paid to production lines to ensure that every plug produced meets the highest quality standards and has no defects. The quality control system was designed to ensure the best possible end product so that customers are assured of receiving a safe and reliable product.

Quick Change
WORKERSBEE air cooling EV plug which has terminal quick change technology. This technology allows the terminal to be replaced in five minutes, which greatly reduces the cost of operation and maintenance. It is a profitable product for charging piles and other fields related to electric vehicle charging.
Easy Operate
EV plug is small and compact.EV Cable is lightweight and easy to operate. Its lightweight construction makes it easy to transport and store away when not in use.
Environmental adaptability
WORKERSBEE EV plug can be used normally in the temperature environment of -30℃-50℃ and can be used well even at an altitude of 4000m.
High Power
Up to 300A output current natural heat dissipation liquid cooling not necessary.Nature cooling is a low-cost, high power, safer electric car charging technology.
Cost-efficient
Air cooling is more cost-efficient and energy-efficient than liquid cooling systems. It requires fewer components and less maintenance, making it a more economical choice for cooling processors.
OEM&ODM
WORKERSBEE EV plug supports customization in terms of LOGO, color, appearance, performance and other aspects. If you meet the MOQ, professional sales and technical staff will arrange everything for you.
What cable sizes and tail-end terminations are supported?
The handle supports common conductor sizes used for 80–300 A DC cables. Termination options follow standard practices (crimped or bolted, depending on cable and kit). Exact conductor range and torque values are provided in the installation guide.
What maintenance is expected and which parts are field-replaceable?
Routine checks cover seals, latch components, microswitch, and strain-relief. Wear parts are accessible and can be replaced on site to reduce downtime; a recommended spares list is available with the service kit.
Is it compatible with our existing GB/T dispensers and bays?
Yes. The connector is designed for mainstream GB/T dispensers and gun holsters. Integration notes include cable outer diameter, minimum bend radius, and signal pin mapping to streamline retrofit and new installs.
Is this plug fully compliant with GB/T and what are its key ratings?
Yes. It conforms to GB/T 20234.3 for DC charging. Typical ratings: up to 1000 V DC, 80–300 A (air-cooled variants), IP55 when mated, −30 °C to +50 °C operating range, and 10,000+ mating cycles.
When is air-cooled sufficient, and when should we consider liquid-cooled?
Air-cooled fits most urban and retail sites with moderate session lengths and normal ambient temperatures. Move to liquid-cooled if you require sustained high currents at high duty cycles, operate in hot climates, or target very short dwell times with peak throughput.
How does the locking and emergency release work in the field?
A motorized lock secures the plug during charging; a mechanical emergency release allows safe disengagement if the session or network control fails. Both mechanisms are designed to protect the vehicle inlet and minimize arcing risk.
