CD-46 Secondary Plug Socket 46-Pins Control Connector for Side-Mounted Vacuum Circuit Breakers – GB3906-91 Compliant Switchgear Accessory

The CD-46 Secondary Plug Socket is a high-reliability 46-pin control connector designed specifically for the secondary control systems of side-mounted vacuum circuit breakers (VCB). This critical accessory facilitates the transmission of vital position signals, including open, closed, and test positions, while enabling automated remote control of switching operations. Built to meet the rigorous GB3906-91 standards for $3 \sim 35\text{kV}$ AC metal-enclosed switchgear, the CD-46 features a durable pin-and-socket structure that ensures stable electrical connectivity. Its robust industrial-grade housing and secure locking mechanism provide exceptional protection for control wiring in demanding medium-to-high voltage power distribution environments.
