The 300-630 A range covers large motor loads — pumps, compressors, conveyors — where thermal bimetals would drift and need recalibration. Class 20 trip curve means it allows up to 20 seconds at 7.2× Ie before tripping, matching the starting profile of high-inertia loads without nuisance trips. The connecting bars simplify panel assembly: no separate wiring between relay and contactor terminals.","metaTitle":"Siemens 3RB1065-2LG0 Electronic Overload Relay, 300-630A","metaDescription":"Siemens 3RB1065-2LG0 electronic overload relay, 300-630A, Class 20, for 3TF68/69 contactors.
