TJ-3-Type Circuit Breaker Feed Mechanism – VD4-40.5 Compatible Handcart for 40.5kV Floor-Type Vacuum Circuit Breakers

The TJ-3-Type Feed Mechanism is a precision-engineered control system designed for 40.5kV floor-type circuit breakers, compatible with VD4-40.5 same-type handcarts. This high-voltage switching component consists of an electric motor, reducer, transmission mechanism, and a heavy-duty propulsion rod. It is specifically built to automate the opening and closing states of the circuit breaker by driving the switching parts into action. Manufactured to meet rigorous electrical safety standards, the TJ-3 mechanism takes into account rated voltage, current, and short-circuit parameters to ensure maximum reliability and operational safety in utility and industrial power distribution networks.
