RS PRO Solid State Relay, 55 A Load, Panel Mount, 530 V ac/dc Load

RS PRO Solid State Relay, 3-Phase ZS Type RZ3A

Brought to you from the trusted brand RS PRO, a solid-state relay from the RZ3A family. This SSR is designed for switching various loads motors, transformers, and heating elements. Offers the capacity of switching high voltages up to 530 VAC RMS and includes an in-built varistor for transient protection especially in heavy industrial applications.

When it comes to higher reliability and load cycle capability this SSR has three semiconductor power units soldered directly onto the direct copper bonded (DCB) substrate and there’s also an in-built LED status indicator for applied control voltage.
