Carlo Gavazzi RGC1A Solid State Relays (SSRs) are single-phase devices designed with an integrated heatsink. These SSRs feature zero cross or instant-on switching, integrated voltage transient protection, and a varistor. The RGC1A SSRs offer power and control terminals that allow for the safe looping of cables. These SSRs also offer a 100kA short circuit current rating according to UL508. The RGC1A SSRs have a rated operational voltage of up to 660VAC and an operational current of up to 85AAC at +40°C. These SSRs are available in Types RGC solid-state contactor “E” connection and “U” connection with widths ranging from 17.5mm up to 70mm.
