Description
905 3PH ZDA 48 25 01, Unison 3 phase SSR Dc to Ac, 25amp – a solid state relay (SSR) from Unison in our solid state relays (ssr) range. A solid state relay switches the load with no moving contacts, so it operates silently and does not wear like a mechanical contactor, which suits heaters, ovens and frequent-switching loads.

Output / load rating
24-480VAC/47-63Hz Upto 25Amp@20ºC AC51a, Zero Cross Over
