Each ZW20 unit integrates the vacuum interrupter, solid-insulated\n          embedded pole, operating mechanism and current transformers into a compact, fully enclosed body\n          suitable for long-term field operation.\n        <\/p>\n\n        <p>\n          With the embedded pole design, the ZW20 vacuum circuit breaker achieves high insulation level and\n          protects the interrupter from moisture, dust and pollution. Together with a stable spring operating\n          mechanism, it delivers reliable opening and closing performance under frequent switching conditions\n          on distribution feeders.\n        <\/p>\n\n        <p>\n          In standard configuration the ZW20 works as a pole-mounted vacuum circuit breaker. When it is\n          equipped with a suitable controller and sensors, the same ZW20 vacuum circuit breaker can be\n          configured as an automatic recloser for feeder protection and distribution automation on 12&nbsp;kV\n          networks.\n        <\/p>\n\n        <p style=\"margin-top:14px;font-size:14px;color:#4b5563;\">\n          For a broader view of XBRELE\u2019s outdoor vacuum

contractors and distributors when selecting the\n        ZW20 vacuum circuit breaker for 12&nbsp;kV overhead distribution networks and recloser projects.\n      <\/p>\n    <\/div>\n\n    <div class=\"faq-grid\">\n      <!-- Q1 -->\n      <details open>\n        <summary>\n          <span>What is the main difference between ZW20 and ZW32?<\/span>\n          <span class=\"faq-icon\">+<\/span>\n        <\/summary>\n        <div class=\"faq-answer\">\n          Both products are outdoor medium-voltage vacuum circuit breakers, but ZW20 is typically used as a\n          pole-mounted switching point on 12&nbsp;kV lines and can be configured as an automatic recloser.\n          ZW32 is a more compact pole-mounted breaker platform with different ratings and outline dimensions.\n          When planning a project, the ZW20 vacuum circuit breaker is often selected where an integrated\n          control cubicle and recloser functions are required.\n        <\/div>\n      <\/details>\n\n      <!-- Q2 -->\n      <details>\n        <summary>\n          <span>Can the ZW20 vacuum circuit breaker be supplied as an automatic recloser?<\/span>\n          <span class=\"faq-icon\">+<\/span>\n        <\/summary>\n        <div class=\"faq-answer\">\n          Yes. By adding a suitable controller, auxiliary CTs\/VTs and wiring, the ZW20 vacuum circuit breaker\n          can be configured as an automatic recloser with programmable protection curves and reclosing\n          sequences. XBRELE can provide a complete ZW20 recloser package or cooperate with the customer\u2019s\n          specified controller brand.\n        <\/div>\n      <\/details>\n\n      <!-- Q3 -->\n      <details>\n        <summary>\n          <span>Where is the ZW20 vacuum circuit breaker typically installed?<\/span>\n          <span class=\"faq-icon\">+<\/span>\n        <\/summary>\n        <div class=\"faq-answer\">\n          The ZW20 vacuum circuit breaker is installed on concrete or steel poles, usually at feeder\n          branches, section points or near pole-mounted transformers. Designers use the outline &amp;\n          mounting dimensions on this page to match cross-arms, brackets and hardware for the 12&nbsp;kV\n          overhead line.\n        <\/div>\n      <\/details>\n\n      <!-- Q4 -->\n      <details>\n        <summary>\n          <span>What protection functions can be implemented with ZW20?<\/span>\n          <span class=\"faq-icon\">+<\/span>\n        <\/summary>\n        <div class=\"faq-answer\">\n          With a suitable protection relay or recloser controller, ZW20 can provide phase over-current,\n          earth-fault protection, sensitive earth-fault, cold-load pick-up and other functions.\n          CTs\/VTs mounted with the ZW20 vacuum circuit breaker supply the necessary signals for metering\n          and protection.\n        <\/div>\n      <\/details>\n\n      <!-- Q5 -->\n      <details>\n        <summary>\n          <span>What documentation and test reports are available for ZW20?<\/span>\n          <span class=\"faq-icon\">+<\/span>\n        <\/summary>\n        <div class=\"faq-answer\">\n          XBRELE can provide outline drawings, terminal diagrams, type-test reports, routine-test reports\n          and factory inspection records for the ZW20 vacuum circuit breaker. For utility or EPC projects,\n          QAP\/ITP documents and FAT witness testing can also be arranged according to the specification.\n        <\/div>\n      <\/details>\n\n      <!-- Q6 -->\n      <details>\n        <summary>\n          <span>What is the typical delivery time for the ZW20 vacuum circuit breaker?<\/span>\n          <span class=\"faq-icon\">+<\/span>\n        <\/summary>\n        <div class=\"faq-answer\">\n          For standard 12&nbsp;kV ZW20 configurations, the typical lead time is about 15\u201325 days after\n          order confirmation. For customized designs with special controllers, CTs\/VTs or testing\n          requirements, lead time is usually 25\u201335 days depending on quantity and project scope.\n        <\/div>\n      <\/details>\n\n      <!-- Q7 \u00b7 external link -->\n      <details>\n        <summary>\n          <span>Which international standards are used as reference for ZW20 testing?<\/span>\n          <span class=\"faq-icon\">+<\/span>\n        <\/summary>\n        <div class=\"faq-answer\">\n          ZW20 outdoor vacuum circuit breakers are designed and type tested with reference to the IEC&nbsp;62271\n          series for high-voltage switchgear, in particular IEC&nbsp;62271-100 for high-voltage AC\n          circuit-breakers.
