Description

Features, Applications

Zero Voltage and Random Turn-On Switching Panel Mount 600V Transient Capability Internal Snubber & 125A Models Available Integrated Overvoltage Protection by Automatic Self Turn-On (Suffix P)

Featuring state-of-the-art Surface Mount Technology, these SPST-NO relays deliver proven reliability in the most demanding applications. Output consists of an SCR AC switch and is available in zero-cross, random turnon (phase controllable) and normally closed (Form B) versions with either or DC input (coil) control. Manufactured in Crydom's ISO 9001 Certified facility for optimum product performance and reliability.
