This circuit board is designed to operate and control the ZN63 (VS1) indoor voltage vacuum circuit breaker. Key benefits Enables reliable control of energy storage, locking, anti, closing, and opening actions for the VS1 breaker, improving switch operation reliability. Flexible installation options supporting both fixed and trolleymounted configurations. Functionality is configurable through different jumper connection methods, allowing tailored control behavior. Builtin rectifier bridge supports operation from both AC and DC power sources, reducing the need for separate power supplies. A small 110V DC relay is employed for anti functionality, contributing to protection features in the control scheme. Main functions Controls energy storage for the voltage circuit breaker Manages locking and anti, closing, and opening circuits Supports multiple control configurations via jumper options Compatibility and installation Applicable to ZN63 (VS1) indoor voltage vacuum circuit breakers Suitable for both fixed installations and trolleymounted setups Jumpers enable different functional configurations to meet installation requirements Power and performance attributes Rectifier bridge enables AC and DC operation 110V DC relay provides anti functionality as described Designed to integrate with existing VS1 control schemes and panel layouts Use scenarios Factory or substation indoor switchgear where fixed VS1 breakers are used, enabling stable energy storage, locking, and open/close control from a single board Mobile or portable testing or maintenance setups that utilize trolleymounted VS1 breakers, benefiting from flexible jumperconfigured functions Upgrade or retrofit projects where a VS1 board replacement is needed to maintain compatibility with ZN63 systems and to utilize AC/DC operation and the anti control relay Notes Size and material specifications are not provided in the description Functionality and performance are described as per the original specifications and model references (ZN63 VS1) without additional modifications or omissions
