GLVAC GLFWB, GLFWS & GLW Series
100A–150A bidirectional high-current DC contactor
The GLVAC GLFWB Series is a ceramic-insulated hermetic DC contactor family distinguished by its bidirectional current interruption capability. Unlike standard GLFW models, GLFWB units provide symmetric switching performance in both current directions — a feature critical in energy storage, V2G (Vehicle-to-Grid), bidirectional EV charging, microgrid systems, and backup power applications.
Two models are offered: GLFWB100 (100A, 35mm² cable, 1000A maximum switching) and GLFWB150 (150A, 50mm² cable, 1500A maximum switching). All models provide 0.5 mΩ low contact resistance and 300,000 mechanical cycle life.
Typical applications: V2G and V2L (Vehicle-to-Load) systems, bidirectional EV charging controllers, ESS charge/discharge contactor, microgrid cut-off circuits, backup power (UPS) DC input, and solar+battery hybrid systems.
