It is designed for motor protection in industrial control panels, providing electronic overload detection with a tripped message output. The 1000 V rated insulation voltage covers 400 V, 480 V, and 690 V line-to-line systems with margin. The adjustable trip classes (5E, 10E, 20E, 30E) let you match the overload trip curve to the motor's starting profile: Class 5E for fast-starting loads like pumps, Class 30E for high-inertia loads like centrifuges or crushers. The relay operates on 50/60 Hz supply and includes temperature compensation over the -25 to +60 °C operating range, so the trip threshold stays within tolerance across ambient temperature swings in the enclosure. This overload relay mounts directly to a contactor or as a stand-alone unit. The fastening method is contactor mounting or stand-alone installation, with busbar connection for the main current circuit. It fits the S10 and S12 frame sizes. The auxiliary switch is integrated, and the relay can be installed in any mounting position. Dimensions are 120 mm width, 119 mm height, and 155 mm depth — the depth is the key panel clearance dimension when mounted on a contactor. Solid and stranded wire connections accept 2x (0.25... 1.5 mm²) for the control circuit. The relay meets substance prohibitance requirements per the 07/01/2006 date (RoHS compliance). Shock resistance is 15g / 11 ms per IEC 60068-2-27, with the signaling contact in tripped position rated at 8g / 11 ms. Vibration resistance covers 1-6 Hz at 15 mm amplitude and 6-500 Hz at 20 m/s² for 10 cycles.","metaTitle":"Siemens 3RB2163-4MF2 SIRIUS Solid-State Overload Relay, 630A","metaDescription":"Siemens 3RB2163-4MF2 SIRIUS solid-state overload relay. 630A thermal current, 1000V rated, adjustable trip classes 5E-30E.
