It covers a 13...50 A adjustment range with Class 20 trip curve — meaning it allows a 20-second thermal memory before tripping on a locked-rotor condition, which is the standard protection band for standard-duty induction motors driving pumps, fans, and conveyors. The screw terminals and manual-only reset (no auto-reset option) suit it for applications where a manual intervention after a fault is preferred — typical in unattended or remote panels where you want a positive reset action before restarting the line.","metaTitle":"Siemens 3RB1035-2UB0 Electronic Overload Relay, 13-50A, Clas","metaDescription":"Siemens 3RB1035-2UB0 electronic overload relay, 13-50A, Class 20, screw connection, manual reset, size S2.
