Class 20 means the relay allows 20 seconds of locked-rotor current before tripping — the standard for general-purpose induction motors driving pumps, fans, and conveyors. Manual reset forces an operator to clear the fault at the panel, preventing automatic restart after a trip. The size S0 footprint matches Siemens 3RT2 contactors in the same frame; screw terminals accept up to 4 mm² stranded wire.","metaTitle":"Siemens 3RB1025-2SB0 Electronic Overload Relay, 3-12A, Class","metaDescription":"Siemens 3RB1025-2SB0 electronic overload relay, 3...12A, Class 20, screw connection, manual reset, size S0.
