Sensata introduces the GXVB611, a high-performance bidirectional DC contactor with integrated auxiliary contact functionality, engineered for reliable and efficient switching in demanding high-voltage environments.
With a rated voltage up to 1000VDC and nominal current ratings up to 600A, this dual-coil contactor is ideally suited for next-generation applications such as megawatt EV charging and a wide range of industrial systems.
At the core of the GXVB611 is a hermetically sealed, gas-filled design that enhances performance, safety, and durability. This advanced construction reduces contact resistance, improves thermal behavior, and ensures consistent operation even under extreme conditions.
Key Features
- Gas-Filled Design – Lower resistance compared to non-hermetic switches, resulting in higher efficiency and reduced heat generation. Fully sealed to IP67 level.
- High Fault Interrupt Capability – Suppression gas enables rapid arc cooling, prevents oxidation, and ensures safe interruption of high fault currents.
- Efficient Dual-Coil Design – Very low continuous 24 VDC coil power with no EMI emissions or cross-talk, ideal for battery-powered and low-power systems.
- Integrated Coil Suppression – Built-in suppression eliminates the need for external components, reducing engineering time and system cost.
- Reliable Performance – Designed for high-voltage DC switching with robust electrical and mechanical characteristics.
- Certified Quality – Compliant with UL 60947-4-1, CE certification pending.
Applications
- DC fast charging
- Energy storage systems
- Battery electric special mobility
