Operating on a 110V L\/L input at 50Hz, this relay corresponds to ANSI device number 27 and de-energizes its output relay on trip as standard, providing volt-free contact output rated at 5A, 250V 50\/60Hz and 24V DC. Adjustable SET (75-100% volts) and DIFF (1-15% volts) dials allow fine-tuning of trip thresholds to match specific system requirements. Manufactured in the UK to CE standards, this relay is built for reliable performance in industrial power monitoring panels. WeSellStocks.co supplies surplus and wholesale industrial electrical components, including hard-to-source protection relays like this Crompton Instruments 252-PVKW unit, to procurement teams, EPC contractors, and MRO buyers across the USA, UAE, and Worldwide. Sourced from verified industrial inventories, this listing supports fast turnaround for power monitoring system maintenance and replacement part needs where OEM lead times are a constraint.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Crompton Instruments\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Voltage Monitoring Protection Relay\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePart Number\u003c\/strong\u003e: 252-PVKW-PMBX-C5-EB\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eIndustry Category\u003c\/strong\u003e: Industrial Electrical Protection \u0026amp; Power Monitoring\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 110 Volts L\/L input\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 5A (contact rating)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePower Rating\u003c\/strong\u003e: Available upon request\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eInput Voltage\u003c\/strong\u003e: 110 Volts L\/L, 50 Hertz\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eOutput Voltage\u003c\/strong\u003e: 250V 50\/60Hz \u0026amp; 24V DC (relay contact output)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: DIN rail \/ panel mount\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eStandards \/ Compliance\u003c\/strong\u003e: CE\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eOther Confirmed Specs\u003c\/strong\u003e: A.N.S.I.
