It provides motor protection by detecting sustained overcurrent conditions and tripping the connected contactor before heat damage occurs. The relay uses a thermal sensing method and is rated Trip Class 10A, meaning it trips within 10 seconds at 7.2 times the set current. Electricians and industrial controls technicians install this device as part of a motor starter assembly in control panels, machine enclosures, and industrial distribution equipment. Its compact form factor makes it suitable for tight panel layouts.\u003c\/p\u003e\u003cp\u003eThe LR3D10 is designed for use in motor protection circuits in both light industrial and commercial applications. It pairs directly with LC1D09 through LC1D38 series contactors to form a complete IEC motor starter. Typical installation scenarios include conveyor drives, pump starters, fan motors, and other three-phase motor loads requiring reliable overload protection. The adjustable current range of 4 to 6 amps makes it appropriate for smaller fractional to low-horsepower motor applications operating on standard IEC voltage systems up to 690 VAC.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThermal sensing method detects sustained overcurrent for reliable motor protection\u003c\/li\u003e\n\u003cli\u003eAdjustable current range from 4 to 6 amps to match motor full-load amperage\u003c\/li\u003e\n\u003cli\u003e690 VAC maximum voltage rating supports a wide range of IEC power systems\u003c\/li\u003e\n\u003cli\u003eTrip Class 10A for fast response to overload conditions\u003c\/li\u003e\n\u003cli\u003eDirect-mount compatibility with LC1D09 and LC1D38 contactors\u003c\/li\u003e\n\u003cli\u003eCompact dimensions fit standard IEC motor starter assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for direct use with LC1D09 and LC1D38 series contactors as stated by the manufacturer.
