The trip class range of 5 through 30 means you can set the thermal memory to match the start profile of the load — Class 10 for standard motor starts, Class 20 for higher-inertia loads like fans or crushers, Class 30 for extended acceleration. The main circuit uses a current transformer for sensing; the auxiliary circuit terminates at screw terminals. Reset is configurable between manual, automatic, and remote. A monostable overload warning output signals a pre-trip condition on AC 110...120 V, 50/60 Hz control voltage. Individual mounting means the relay clips directly onto the contactor or onto a DIN rail adapter for the S00/S0 frame. The screw-terminal auxiliary circuit accepts ferruled stranded or solid conductors; torque to the terminal marking on the housing. The current-transformer sensing circuit is self-powered from the main circuit — no separate control supply needed for the overload detection, only for the warning output coil.","metaTitle":"Siemens 3RB1246-1QG10 Overload Relay, 6.3-25 A, Size S00/S0","metaDescription":"Siemens 3RB1246-1QG10 overload relay, 6.3...25 A, size S00/S0, Class 5...30, AC 110-120 V 50/60 Hz.
