style=\"margin:0 0 16px;line-height:1.7\">Vacuum contactors switch medium-voltage AC loads such as motors, transformers, and capacitor banks. The arc is extinguished inside a vacuum interrupter at a natural AC current zero.<\/p>\n<h3 style=\"margin:28px 0 12px\">Can a vacuum contactor switch DC circuits?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">DC has no natural current zero, so vacuum interruption loses its core advantage there. HV DC paths are normally specified with DC-rated sealed electromagnetic contactors whose tables publish DC voltage and DC-1 current lines.<\/p>\n<h3 style=\"margin:28px 0 12px\">Does SAYOON sell vacuum contactors?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">No. The live SAYOON catalog lists epoxy resin sealed electromagnetic HV DC contactors \u2014 the SEV and HEV series \u2014 and no vacuum contactor SKUs. Vacuum requirements belong with vacuum technology suppliers.<\/p>\n<h3 style=\"margin:28px 0 12px\">What is inside a sealed electromagnetic DC contactor?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Main contacts operate inside an epoxy resin sealed chamber driven by a DC coil. Cited SEV pages publish IP68 protection and -40 to +85 C ambient bands for that sealed construction.<\/p>\n<h3 style=\"margin:28px 0 12px\">Which SEV fields should an HV DC RFQ quote?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Quote contact voltage span, DC-1 load current, contact form, coil power line, maximum switching current, and the IP and ambient rows \u2014 each from the exact SKU page, such as SEV100AD or SEV800AH.<\/p>\n<h3 style=\"margin:28px 0 12px\">When should a buyer stay with vacuum technology?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Stay with vacuum when the duty is genuinely medium-voltage AC switching or when an existing MV switchgear standard and spare pool is built around vacuum bottles.<\/p>\n<h3 style=\"margin:28px 0 12px\">Where should an HV DC contactor shortlist start on this site?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Start at the SEV series pillar, shortlist by published voltage and current lines, then send the duty profile through the contact page for datasheet-level confirmation.<\/p>","protected":false},"excerpt":{"rendered":"<p>A vacuum contactor wins when the duty is medium-voltage AC motor and transformer switching, where the arc is quenched at natural current zeros inside a vacuum interrupter; an epoxy sealed electromagnetic DC contactor wins on HV DC battery, PV, and drive paths, because DC interruption and sealed bidirectional switching are what published SEV-class tables are specified for \u2014 and SAYOON&#8217;s published catalog covers the electromagnetic side only.
