H12D4825D pdf
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.

GENERAL NOTES
© 2003 CRYDOM CORP, Specifications subject to change without notice.
All parameters at 25˚C and per section unless otherwise specified.
Off-State dv/dt test method per EIA/NARM standard RS-443, paragraph 13.11.1
Heat sinking required, for derating curves see page 2.
.comTurn-on time for random turn-on (-10) versions is 0.1 msec.
Crydom Heat Sinks offer excellent thermal
management and are perfectly matched to the
load current ratings of Crydom panel mount
relays. Request Crydom's Heat Sink specifica-
tion sheet for all the details.
