It switches 90 A continuous at 48-460 VAC, controlled by a 24 VDC input. Switching is instantaneous (zero-cross or random-fire depending on the variant; this order code is the instantaneous-switching version, meaning it turns on immediately with the control signal, suited for phase-angle control or fast cycling). The 90 A rating is the continuous load current at the rated voltage range. Because this is a solid-state relay with no moving contacts, it handles high inrush loads (like motor starts or lamp loads) without wear, but it does generate heat proportional to the load current. The listing explicitly states 'for mounting on available cooling surfaces' — this part requires a heatsink or a metal panel for thermal management; it is not free-air rated at 90 A. RoHS compliant since 15 January 2024. Export control: AL N / ECCN N, no restrictions for most industrial buyers.","metaTitle":"Siemens 3RF3190-1BA04 SIRIUS 3RF31 SSR, 90 A, 48-460 VAC","metaDescription":"Siemens 3RF3190-1BA04 SIRIUS solid-state relay, 1-pole 22.5 mm, 90 A continuous, 48-460 VAC/24 VDC control.
