That 90 A figure is the nominal continuous current through the output semiconductor — it's the rating you size the load cable and upstream protection for, not a surge or inrush figure. For resistive heater loads or lamp banks, this relay switches the full 90 A within the voltage window. For motor or transformer loads with high inrush, you'd typically derate per the manufacturer's guidelines; the 90 A continuous rating gives you the headroom for steady-state current after the start transient settles. ## Panel integration and form factor The 45 mm width (3SU form factor) mounts on standard DIN rail. The screw terminals accept the load and control wiring directly — no separate base or socket required. Packaging dimensions are 62 x 47 x 74 mm, single piece per unit. The 24 VDC control side is optically isolated from the power side, which simplifies panel wiring: you can run the DC control loop from a separate power supply without worrying about common-mode voltage on the AC line.","metaTitle":"Siemens 3RF3090-1AA04 SIRIUS 3RF30 SSR, 90 A, 48-460 VAC, 24","metaDescription":"Siemens SIRIUS 3RF30 solid-state relay, 1-pole 45 mm, 90 A rated 48-460 VAC with 24 VDC control.
