Series H12
25-90Amp 鈥?480 Vac 鈥?AC Output
鈥?1200 Volt Blocking
鈥?Panel Mount
鈥?Up to 660 Vac
鈥?Zero Voltage Switching
and Random Turn-On
鈥?SCR Output
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, H12CD and H12WD are
snubberless (reduced leakage current).
Manufactured in Crydom鈥檚 ISO 9002
Certified facility for optimum product
performance and reliability.
