Product details

What This Relay Does

The Siemens 3RB1025-1RB0 is an electronic overload relay sized for small motor loads in the 0.1 to 0.4 A range. 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. Submit an RFQ and we'll pull current availability.
