What it is and what it does
The 3RB1246-1QG01: The main circuit uses a current transformer for sensing, while the auxiliary circuit terminates on screw terminals. Reset options include manual, automatic, and remote, with bistable outputs and ground-fault signaling built in. The control supply is AC 110 to 120 V at 50/60 Hz.
Deployment context
Rated for individual mounting on Size S00 or S0 contactors, this relay integrates into standard motor starter assemblies in control panels. The 6.3–25 A range covers fractional to moderate-horsepower motors on conveyor, pump, and fan loads.
