For a standard <strong>VS1-12kV VCB<\/strong>: 630A uses \u03a635mm contacts, 1250A uses \u03a649mm, and 3150A uses \u03a6109mm. Always verify the number of sheets (e.g., 30 vs 64 sheets) and the outer diameter in our <strong>technical drawings<\/strong> before ordering.\n          <\/div>\n        <\/details>\n\n        <details>\n          <summary>What is the silver plating thickness on contacts?<\/summary>\n          <div class=\"faq-ans\">\n            All our <strong>tulip contacts<\/strong> and static contacts feature a standard silver plating thickness of <strong>8-12\u03bcm<\/strong>. This ensures low contact resistance and prevents oxidation, which is critical for minimizing temperature rise in high-current <strong>switchgear contacts<\/strong>. Thicker plating is available upon request.\n          <\/div>\n        <\/details>\n\n        <details>\n          <summary>Are these parts compatible with ABB VD4 breakers?<\/summary>\n          <div class=\"faq-ans\">\n            Yes. XBRELE manufactures aftermarket <strong>VCB replacement parts<\/strong> that are dimensionally compatible with major brands like ABB (VD4), Siemens (3AH), and Schneider (Evolis). Specifically, our GC5 series <strong>tulip contacts<\/strong> are a direct fit for most VD4 and VS1 type vacuum circuit breakers.\n          <\/div>\n        <\/details>\n\n        <details>\n          <summary>What material is used for the Contact Arms?<\/summary>\n          <div class=\"faq-ans\">\n            For currents up to 1250A, we offer cost-effective Copper-Aluminum (Cu-Al) composite arms. For high currents (1600A-4000A), we strictly use pure <strong>T2 Copper<\/strong> arms to ensure maximum conductivity. All arms are insulated with <strong>APG epoxy resin<\/strong> or vulcanized rubber for dielectric safety.\n          <\/div>\n        <\/details>\n\n      <\/div>\n\n      <div style=\"display:flex; flex-direction:column; gap:20px;\">\n\n        <details>\n          <summary>Can you supply custom Insulating Rods?<\/summary>\n          <div class=\"faq-ans\">\n            Yes. While we stock standard lengths (e.g., 180mm, 235mm) for <strong>VS1 spare parts<\/strong>, we can manufacture custom <strong>insulating operating rods<\/strong> (pull rods) with specific lengths and thread sizes (M12\/M16) based on your sample or drawing.\n          <\/div>\n        <\/details>\n\n        <details>\n          <summary>What is the difference between Epoxy and Vulcanized arms?<\/summary>\n          <div class=\"faq-ans\">\n            <strong>Epoxy resin arms<\/strong> are rigid and offer excellent mechanical support, ideal for standard 12kV cabinets. <strong>Vulcanized arms<\/strong> (used in ZN85 40.5kV) have a silicone rubber coating that provides better flexibility and surface creepage resistance, suitable for heavy-duty or humid environments.\n          <\/div>\n        <\/details>\n\n        <details>\n          <summary>How often should VCB contacts be replaced?<\/summary>\n          <div class=\"faq-ans\">\n            <strong>Vacuum circuit breaker contacts<\/strong> should be inspected annually. Replacement is recommended if the silver plating is worn off, if there are signs of pitting\/burning, or if the contact resistance exceeds the manufacturer&#8217;s limit (typically >50\u03bc\u03a9). Regular maintenance ensures the safety of your <strong>switchgear system<\/strong>.\n          <\/div>\n        <\/details>\n\n        <details>\n          <summary>Do you sell Earthing Switch contacts?<\/summary>\n          <div class=\"faq-ans\">\n            Yes. We supply <strong>flat contacts<\/strong> (duckbill type) specifically for JN15 earthing switches. These are available in 10kV and 35kV ratings.
