Carlo Gavazzi Solid State Relay 1-Phase Zero-Cross RAM1A60A50

Carlo Gavazzi Solid State Relay 1-Phase Zero-Cross with LED, Control: 20-280VAC/22-48VDC, Operational: 600VAC, 50A.

The industrial, 1-phase relay with antiparallel thyristor output is the most widely used industrial SSR due to its multiple application possibilities. The relay can be used for resistive, inductive and capacitive loads. The zero switching relay switches ON when the sinusoidal curve crosses zero and switches OFF when the current crosses zero. The instant-on relay with DC control input can be used for phase angle control. The built-in snubber secures transient protection. The LED indicates the status of the control input. The clip-on cover secures touch protection (IP 20). Protected output terminals can handle cables up to 16 mm2.
