H12D4825D

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 panelmount package. Utilizing an AC switch output with internal snubber, relays provide greater protection against false triggering. Model choices include zerovoltage or random turn-on (phase controllable) switching. Manufactured in Crydom's ISO 9001 Certified facility for optimum product performance and reliability.
