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.

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.
