The 3RB1262-0LG30: The relay includes integrated ground fault detection and provides a separate overload warning output. Reset options are manual, automatic, or remote, and the auxiliary circuit terminates on screw terminals while the main circuit connects via busbar. Control voltage is AC 110-120 V, 50/60 Hz. The monostable outputs drop out on coil power loss, which is expected for fail-safe behavior in a motor protection circuit.
The 200-820 A range and S10/S12 frame size narrow drop-in options. Verify mounting footprint and busbar interface before specifying an alternative.
