The 24 VDC coil uses spring-loaded terminals, and the relay is designed to be mounted on a cooling surface — that's the heatsink or panel metal it clamps to, not free-air like a contactor. At 22.5 mm wide, it fits a standard DIN-rail footprint but needs that thermal interface to shed the heat a 50 A SSR generates. ## Where it goes and what it handles This SSR handles resistive or light inductive loads in control panels — heater banks, lamp banks, solenoid valves, transformer primaries. Mounting matters with this part: it's designed to clamp to a cooling surface, so the panel builder needs to account for thermal paste or a thermal pad between the relay base and the mounting plate. Without that heat path, the 50 A rating isn't usable in continuous duty. RoHS compliance is effective since 15-01-24, so units shipped after that date meet the EU directive.","metaTitle":"Siemens 3RF3150-2AA06 SIRIUS 3RF31 SSR, 50 A, 48-600 VAC, 24","metaDescription":"Siemens 3RF3150-2AA06 SIRIUS 3RF31 solid-state relay, 1-pole, 22.5 mm, 50 A, 48-600 VAC, 24 VDC coil, spring-loaded terminals.

The nearest sibling would be a 50 A unit with a different coil voltage (e.g., 110-230 VAC instead of 24 VDC) or a variant with screw terminals instead of spring-loaded. The pinout and mounting footprint are shared across the family, so swapping between them is straightforward if the coil voltage matches the control circuit."},{"question":"What is the group code and product group for 3RF3150-2AA06?","answer":"The Group Code is R711 and the Product Group is 3725.
