The three-phase\n          vacuum interrupters and main conductive parts are arranged in a compact structure and embedded\n          in epoxy insulation, which shortens the insulation distance, reduces the overall depth of the\n          breaker and enhances dielectric performance under operating conditions.\n        <\/p>\n\n        <p>\n          The spring operating mechanism is installed within the circuit breaker frame and matched with\n          the upper\u2013lower layout of the primary circuit, resulting in smooth motion transmission and\n          reliable mechanical behavior. This design makes the ZN85 suitable for frequent switching duty\n          with long electrical and mechanical life while keeping routine maintenance requirements low.\n        <\/p>\n\n        <p>\n          Thanks to its compact outline, flexible operation and high breaking capacity, the ZN85 series\n          is widely used in indoor switchgear cubicles as an incoming or outgoing feeder
