Class 10 trip means it will ride through normal starting inrush on standard induction motors but still protect against prolonged overloads — the right balance for most general-purpose machinery. The manual-only reset (no auto-reset option) is a safety consideration: the relay stays tripped until someone physically presses the reset button, preventing unexpected restart after a fault.","metaTitle":"Siemens 3RB1025-1NB0 Electronic Overload Relay, 0.4-1.6A, Cl","metaDescription":"Siemens 3RB1025-1NB0 electronic overload relay, 0.4-1.6A, Class 10, screw connection, manual reset, size S0.
