Operating on Trip Class 20, it provides a longer trip time suited for high-inertia loads that require extended ramp-up time. The relay uses thermal sensing to monitor current draw and trips the circuit when sustained overcurrent is detected. Installation is handled by licensed electricians working on industrial motor control panels and starters. It pairs directly with compatible IEC contactors to form a complete motor starter assembly.\u003c\/p\u003e\u003cp\u003eThis overload relay is intended for industrial and commercial motor control applications where IEC-rated components are specified. It is designed for use with the LC1D80 and LC1D95 contactors, making it a direct-fit component for motor starter configurations in those contactor families. Typical installations include conveyor drives, pump panels, compressor controls, and other equipment requiring reliable thermal motor protection at the 63 to 80 amp range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThermal sensing method monitors motor current for reliable overload detection\u003c\/li\u003e\n\u003cli\u003eCurrent range of 63 to 80 amps covers high-horsepower motor applications\u003c\/li\u003e\n\u003cli\u003e690 VAC rating suitable for international and domestic industrial voltage systems\u003c\/li\u003e\n\u003cli\u003eTrip Class 20 allows extended trip delay for high-inertia motor loads\u003c\/li\u003e\n\u003cli\u003eDirect-mount compatibility with LC1D80 and LC1D95 IEC contactors\u003c\/li\u003e\n\u003cli\u003eCompact form factor at 4.8 x 3.5 x 3.2 inches for panel space efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the LC1D80 and LC1D95 IEC contactors as part of a complete motor starter assembly.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Disconnect and lock out all power to the motor control panel before mounting or wiring the relay. The relay should be mounted directly to its compatible contactor before securing panel connections.
