This capability ensures that the device can safely close onto a fault current without welding the contacts or causing mechanical failure, protecting the operator.\n        <\/div>\n      <\/details>\n\n      <details>\n        <summary>\n          <span>What is the difference between JN15 and EK6 models?<\/span>\n          <span class=\"faq-icon\">+<\/span>\n        <\/summary>\n        <div class=\"faq-answer\">\n          While both are indoor AC <strong>HV safety components<\/strong> for 12kV systems, they differ in structural design. The <strong>JN15<\/strong> is a widely used integrated design with a compact footprint, whereas the <strong>EK6<\/strong> follows the classic ES1 prototype design with an assembly structure. Both meet the same electrical performance standards.\n        <\/div>\n      <\/details>\n\n      <details>\n        <summary>\n          <span>Can the soft connection length be customized?<\/span>\n          <span class=\"faq-icon\">+<\/span>\n        <\/summary>\n        <div class=\"faq-answer\">\n          Yes. The standard copper braid length (L) is typically 240mm. However, for special cabinet designs or retrofitting projects, we can customize the length of the <strong>soft connection<\/strong> to ensure proper flexibility and alignment with the main busbar. Please specify the required length (L) when ordering.\n        <\/div>\n      <\/details>\n\n      <details>\n        <summary>\n          <span>How does the device integrate with voltage indicators?<\/span>\n          <span class=\"faq-icon\">+<\/span>\n        <\/summary>\n        <div class=\"faq-answer\">\n          Our <strong>switch assemblies<\/strong> can be equipped with insulators containing embedded capacitive sensors. These sensors connect to a DXN-type live display unit (VPIS) on the cabinet door, allowing operators to visually confirm that the circuit is de-energized before operating the <strong>grounding mechanism<\/strong>.\n        <\/div>\n      <\/details>\n\n      <details>\n        <summary>\n          <span>Is this component compatible with motor operators?<\/span>\n          <span class=\"faq-icon\">+<\/span>\n        <\/summary>\n        <div class=\"faq-answer\">\n          Yes, the operating shaft is designed to couple with both manual handles and electric motor drive mechanisms. This allows for remote operation and integration into automated <strong>distribution automation systems<\/strong>, enhancing safety by keeping personnel away from the arc flash boundary.\n        <\/div>\n      <\/details>\n\n      <details>\n        <summary>\n          <span>What maintenance is required for these mechanical parts?<\/span>\n          <span class=\"faq-icon\">+<\/span>\n        <\/summary>\n        <div class=\"faq-answer\">\n          These <strong>indoor MV components<\/strong> are designed for long service life (Class M1, 2,000 operations). Routine maintenance typically involves visual inspection of the contacts for wear, verifying the torque of terminal bolts, and checking the lubrication of the spring mechanism every 3-5 years or after a short-circuit event.\n        <\/div>\n      <\/details>\n\n    <\/div>\n  <\/div>\n<\/section>\n<\/div><\/div><\/div>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Switchgear Safety Components Indoor HV Earthing Switches (12kV &#8211; 40.5kV) XBRELE\u2019s Earthing Switches (JN15 &#038; EK6 Series) provide reliable safety grounding for KYN28\/KYN61 switchgear.
