PAGE 1 OF 3

High voltage relays use IC driven cir-

cuits for switching loads up to 660

VAC. All models come with 1200

Volts blocking.

Type H12WD is a snubberless

(reduced leakage current).

Manufactured in Crydom’s ISO 9001

Certified facility for optimum product

performance and reliability.
