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 9002
Certified facility for optimum product
performance and reliability.
Dual Relays
25-40Amp • 120/240, 480 Vac • AC Output
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.
