Multi-Tap Control Transformers with Breaker


The 694 Series multi-tap control transformers with breakers are industrial-grade multi-tap step down voltage transformers with manual resettable current-limiting secondary circuit breakers. Engineered for Building Automation Systems, BAS, and industrial applications, these transformers are ideal for use in temperature control applications. Each transformer with circuit breaker combination is UL listed and provides 24 volt AC control voltage from a 120-480 volt AC primary supply. The leads are clearly marked for ease of wiring. These foot-mounted transformers are designed for NEMA 1 locations and should be installed in compliance with all national and local electrical codes.
