Carlo Gavazzi RGC3P Solid State Relays are 3-pole analog switching solid-state contactors that feature a rated operating voltage of up to 660VAC. RGC3P relays feature switching modes that cover phase angle control, distributed full-cycle control, and soft-start for limiting the inrush current of loads that have a high-temperature coefficiency, such as short wave infrared heaters. Additional features include integrated detection of mains loss, load loss, SSR short-circuit, and overtemperature. Carlo Gavazzi RGC3P Relays have an alarm condition that is signaled through an EMR output and is visually indicated by the alarm LED.
