The 6.3...25 A range covers small to medium motor loads (pumps, fans, conveyors). The ground fault detection function is non-standard on basic overloads; this relay signals ground faults via monostable outputs, useful for leakage monitoring on ungrounded or IT systems. Screw terminals on the aux circuit match standard panel wiring practices.","metaTitle":"Siemens 3RB1246-1QM20 Overload Relay 6.3-25 A, Discontinued","metaDescription":"Siemens 3RB1246-1QM20 discontinued overload relay, 6.3-25 A for S00/S0 motor protection, class 5-30, ground fault detection, 220-240 VAC.
