It protects AC motors up to 132 kW at 500 V / 50 Hz, with a CLASS 10E trip curve that clears overloads before the winding insulation degrades on standard induction motors. The auxiliary switch is integrated, and the relay signals a 'tripped' message on its status output. Rated operational current is 200 A at both 480 V and 600 V — that's the continuous current the relay can carry without overheating, so it's sized for motor full-load amps up to that figure. The thermal current (Ith) is also 200 A, meaning the main current path is rated for that continuous load regardless of voltage. The auxiliary contacts are rated for 2 A at 24 V, 4 A at 120 V, and 3 A at 230 V — enough to drive a PLC input or a small contactor coil directly. Mounts directly onto a contactor (contactor mounting) or as a stand-alone unit on a panel. Fastening method is M8 bolts for the main contacts; the main current circuit connects via busbar connection. Vibration resistance is 1–6 Hz at 15 mm amplitude and 6–500 Hz at 20 m/s² for 10 cycles; shock resistance is 15 g for 11 ms per IEC 60068-2-27. That makes it suitable for machine-mounted applications on conveyors, pumps, and compressors where vibration is present.","metaTitle":"Siemens 3RB2056-1FC2-ZX95 SIRIUS solid-state overload relay,","metaDescription":"Siemens SIRIUS 3RB2056-1FC2-ZX95 solid-state overload relay, CLASS 10E trip, 200 A thermal current, 1000 V rated.
