High voltage relays use IC driven cir-
cuits for switching loads up to 660
VAC. All models come with 1200
Volts blocking and are available with
either AC or DC input (coil) control.
Types H12CA and H12CD are
snubberless (reduced leakage current).
Manufactured in Crydom’s ISO 9001
Certified facility for optimum product
performance and reliability.
