H12CD4850 Datasheet, PDF (1/3 Pages) List of Unclassifed Manufacturers – 50-90Amp 480 Vac AC Output

Series H12C
50-90Amp • 480 Vac • AC Output
• 1200 Volt Blocking
• Panel Mount
• Up to 660 Vac
• Zero Voltage and Random
Turn-On
• SCR Output
• Integrated Overvoltage
Protection by Automatic
Self Turn-On (Suffix P)
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.
