Dual Relays
25-40Amp 鈥?120/240, 480 Vac 鈥?AC Output
鈥?Zero Voltage and Random
Turn-On Switching
鈥?SCR Output
鈥?Industry Standard Package
鈥?Panel Mount
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鈥檚 ISO 9002
Certified facility for optimum product
performance and reliability.

GENERAL NOTES
聦
All parameters at 25潞C and per section unless otherwise specified.
聧
Off-State dv/dt test method per EIA/NARM standard RS-443, paragraph 13.11.1
聨
Heat sinking required, for derating curves see page 2.
聫
Turn-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鈥檚 Heat Sink specifica-
tion sheet for all the details.
