Sensata Crydom Solid State Relay Single Phase GNA5, SPST-NO, 25A, 280V, Screw Terminal

Semiconductor relay for DC voltage with built-in FET transistor. Semiconductor relay for AC voltage with triac. Zero voltage switching and integrated transient protection on the output. Replaces relays and contactors when long life and silent switch-on/-offs are required. Must be mounted on a cooling surface, unless the load and ambient temperature are low.
