The 3RF3412-1BB06 from Siemens is a 3-phase industrial solid state relay containing three normally open, zero-cross-over relays. It offers a switching capacity of 25 A, a Phase-to-Phase isolation rating of 1 kV, and a dielectric voltage rating of 600 VAC for all three input and output circuits. Its operating frequency range is between 50 Hz and 60 Hz, and with its wide operating temperature range of -25°C ~ +70°C it can withstand extreme temperatures. This solid state relay is suitable for many general-purpose applications that require reliable switching of electrical circuits in industries such as manufacturing, automotive, and IT.
