Series H12  
25-90Amp • 480 Vac • AC Output  
High voltage relays use IC driven cir-  
• 1200 Volt Blocking  
• Panel Mount  
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).  
• Up to 660 Vac  
• Zero Voltage Sw itching  
and Random Turn-On  
Manufactured in Crydom’s ISO 9002  
Certified facility for optimum product  
performance and reliability.
