These transformers provide power to 24 Vac circuits in heating/cooling control systems. Although the transformers are
typically used in heating/cooling control systems, they can be used in any application that does not exceed the load
ratings. They include a button for manually resetting the circuit breaker. They meet National Electrical Code Class 2 “not
wet” and Class 3 “wet” requirements and are Underwriters Laboratories (UL) Inc. listed under UL 1585. Transformers can
be foot-mounted or conduit/panel mounted. See Table 1 for additional specifications.
