The manual reset forces an operator to visit the panel and verify the fault before restarting, which is the right call for a pump or conveyor where an automatic restart could be a safety issue. Screw terminals keep the wiring straightforward for panel builders who prefer a Phillips driver over a cage-clamp tool. No fiddling with special connectors. For BOM planning, the 3RB1025-1RB0 is a standard catalog item.
