nect terminals. The Series EZ is the
preferred choice for replacement of
120V and 240V Electro-mechanical
relays. Output consists of an SCR
switch and is available in Zero-Cross
and Random Turn-On (Phase
Controlable) versions.

Manufactured in Crydom’s ISO 9001
Certified facility for optimum product
