When the current exceeds the selected setting for a sufficient period, the relay trips and operates its auxiliary contacts to interrupt the motor control circuit. This helps reduce the risk of motor overheating and damage caused by prolonged excessive current.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eProduct Features\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eBrand:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Himel\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eModel:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e HDR3s2518\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eProduct Type:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Thermal Overload Relay\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eAdjustable Current Range:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 12A–18A\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eCompatible Contactor Series:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Himel HDC-18 to HDC-38, subject to verification\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eMain Function:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Electric motor overload protection\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eOperating Principle:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Thermal overload detection\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eApplication:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Motor starters and electrical control panels\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan\u003eApplications\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eThe Himel HDR3s2518 Thermal Overload Relay is suitable for compatible motor control installations, including:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eIndustrial motor starter assemblies\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eWater pumps and pumping systems\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eVentilation fans and blowers\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eCompressors and industrial machinery\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eProduction equipment and motor-driven systems\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eElectrical control panels and motor control circuits\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan\u003eAdjustable Motor Protection\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eThe 12A–18A adjustment range allows the relay to be configured according to the protected motor's rated current and the manufacturer's recommended settings.
