Carlo Gavazzi Solid State Relay 1-Ph. ZS, RF1A23M25

Carlo Gavazzi Solid State Relay 1-Phase Zero Switching with LED & Built-In Transil, Control: 12VDC, Operational: 230VAC, 25A, Fast-On Terminal

The RF1 series provides a compact solid state switching solution suited for confined spaces. Long life time is ensured by the use of assembly technology that reduces stresses on the power semiconductors. The RF1 series is suitable for resistive loads. The zero switching type (RF1A), switches ON when the voltage crosses zero. The instant-ON type (RF1B), switches on when the control voltage is applied. Switch OFF occurs when current crosses zero. Integrated transils provide protection against overvoltage. A green LED indicates presence of the control voltage. FASTON terminals enable fast installation. The RF1 is provided with pre-attached thermal interface ready for mounting on chassis or heat sink.
