It mounts directly to a contactor (contactor mounting,) and offers adjustable trip classes 5E, 10E, 20E, and 30E, letting you match the thermal memory to the motor start profile — fast for short acceleration, slow for high-inertia loads like fans or centrifuges. Shock resistance of 15g / 11 ms confirms it holds calibration under vibration from contactors and motor starters. The auxiliary and control circuit uses spring-loaded terminals — no screw tightening needed, which speeds panel wiring and eliminates torque-check steps. Main current circuit terminals are screw-type, accepting 2x (0.25... 1.5 mm²) solid or finely stranded with ferrule, or 2x (18... 14) AWG. ATEX certification PTB 06 ATEX 3001 Ex II (2) GD permits installation in Zone 2 gas and Zone 22 dust hazardous areas when paired with an appropriate contactor — a key differentiator for chemical, grain, or pharmaceutical lines. ## Deployment context Mounts directly onto a Siemens contactor (contactor mounting,) in any orientation, saving DIN-rail space in the panel. For compliance documentation, the relay carries RoHS substance prohibitance dated 07/01/2006 and surge/burst immunity per IEC 61000-4-4 severity level 3.","metaTitle":"Siemens 3RB2113-4PD0 SIRIUS Solid-State Overload Relay, 3-Po","metaDescription":"Siemens 3RB2113-4PD0 SIRIUS solid-state overload relay, 3-pole, adjustable trip classes 5E-30E, ATEX Ex II (2) GD.
