GB/T DC Fast Charger for EV, Socket, Single Phase, 750V, 250A
Introduction
The GB/T DC Fast charger is engineered for high-power direct current charging applications, fully compliant with GB/T 20234.2-2015. Designed as a DC socket connector, it supports single-phase DC charging with a rated voltage of 750V and a high current capacity of 250A, enabling a maximum charging power of up to 187kW. This makes it ideal for fast-charging stations requiring stable, efficient, and continuous energy delivery.
The connector features a high-strength thermoplastic housing combined with silver-plated copper alloy contacts, ensuring excellent electrical conductivity, low contact resistance, and long-term durability under high current loads. With an IP65 protection rating and UL94 V-0 flame-retardant level, the socket is well-suited for demanding outdoor and industrial environments, offering reliable performance against dust, moisture, and heat. Optimized for professional EV charging infrastructure, the connector supports a wide operating temperature range from -30°C to +50°C and is compatible with heavy-duty cable configurations, including 2×35mm² + 1×16mm² + 2×4mm² + 2P(3×16mm²) wiring. Its robust mechanical and electrical design ensures safe, stable, and high-efficiency DC fast charging across commercial and public charging applications.
