Featuring an adjustable Hz Level setting from 40 to 60 Hz and adjustable hysteresis from 0.3 to 3, this relay provides precise, field-configurable protection for generators, motors, and power distribution systems sensitive to frequency deviation. The unit supports multiple supply\/monitored input voltage and frequency combinations, including 110VAC, 230VAC, and 400VAC ranges across 40-63Hz and 50-73Hz bands, with relay contacts rated up to 8A at 250V AC1. Optional configurations include integral time delay and fixed 1% hysteresis, giving engineers flexibility for demanding protection schemes. CE marked and RoHS compliant, the 45 OFR is built to meet recognized European electrical safety standards. WeSellStocks.co supplies surplus and wholesale electrical protection relays to procurement teams, EPC contractors, and MRO buyers across the USA, UAE, and Worldwide. Power system engineers and distributors sourcing genuine Broyce Control over frequency relays for generator protection, panel builds, or OEM replacement will find the 45 OFR a dependable, precision-adjustable option.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch4 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eTechnical Specifications:\u003c\/h4\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: Broyce Control Ltd\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Over Frequency Monitoring 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: 45 OFR\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eIndustry Category\u003c\/strong\u003e: Electrical Protection \/ Power Monitoring Relays\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHz Level Range\u003c\/strong\u003e: 40–60 Hz (adjustable)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHz Hysteresis Range\u003c\/strong\u003e: 0.3–3 (adjustable)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSupply\/Monitored Input Voltage\u003c\/strong\u003e: 110VAC \/ 230VAC \/ 400VAC ±25%, 40-63Hz or 50-73Hz\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eContact Ratings\u003c\/strong\u003e: 8A 25V DC1; 8A 250V AC1; 3A 250V AC15\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eConfigurable Options\u003c\/strong\u003e: Integral Delay (Option 1); Fixed Hysteresis 1% (Option 2)\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, screw terminal connections\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, RoHS, C-Tick (N3522)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Made in England\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch4 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eApplication:\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe 45 OFR over frequency relay is used to protect generators, motors, and electrical distribution systems from damage caused by excessive supply frequency, commonly in standby power, industrial generation, and critical power monitoring applications.
