H12D4825DE Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – 25-40Amp 120/240, 480 Vac AC OUTPUT
Dual Relays
25-40Amp • 120/240, 480 Vac • AC OUTPUT
• Zero Voltage and Random
Turn-On Swi tching
• SCR Output
• Industry Standard Package
• Panel M ount
Two totally independent AC output
relays come in a single standard panel-
mount package. Utilizing an AC switch
output with internal snubber, relays
provide greater protection against false
triggering. Model choices include zero-
voltage or random turn-on (phase con-
trollable) switching.
Manufactured in Crydom's ISO 9001
Certified facility for optimum product
performance and reliability.
