It provides motor overload and phase-loss protection by detecting excess heat generated by sustained overcurrent conditions. The relay operates on Trip Class 10A, which defines the maximum tripping time under overload conditions and suits standard motor loads in industrial and commercial electrical systems. Licensed electricians and industrial maintenance technicians install this relay as a protective device in motor starter assemblies.\u003c\/p\u003e\u003cp\u003eThe LRD3322 is designed for use in motor control applications requiring IEC-style overload protection. It is specified for installation with the LC1D80 and LC1D95 contactors, making it suited for motor starters in commercial HVAC equipment, pump systems, compressors, and similar three-phase motor loads. It fits residential, light commercial, and industrial panels where IEC motor control components are specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThermal sensing method detects sustained overcurrent and triggers automatic trip response\u003c\/li\u003e\n\u003cli\u003eTrip Class 10A rating suits standard induction motor applications\u003c\/li\u003e\n\u003cli\u003eWide adjustment range of 17 to 25 amps allows field calibration to motor full-load amperage\u003c\/li\u003e\n\u003cli\u003eRated to 690 VAC for compatibility with international and domestic motor control voltage systems\u003c\/li\u003e\n\u003cli\u003eCompatible with LC1D80 and LC1D95 contactors for direct mounting in starter assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with LC1D80 and LC1D95 contactors as an IEC-style overload relay in motor starter assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the NEC and any applicable local codes.
