RIB Relays TR75VA005 Transformer

The TR75VA005 Transformer delivers reliable power for building automation and control systems. This Class 2 current-limiting transformer provides a 24 V AC secondary and supports a flexible primary voltage range of 480/277/240/120 VAC at 50/60 Hz, making it ideal for mixed electrical environments.

With a 75 VA power rating, split-bobbin construction, and RoHS compliance, this transformer combines safety with long-term performance. It is UL-listed for Canada and the US, and CE approved, ensuring compatibility with global installations.

Key features engineered for easy installation and reliable operation include a mounting foot and a 0.5 inch threaded hub, plus 9.5 inch wire leads with a 0.5 inch strip for secure terminations. The compact footprint fits compact panels while delivering stable output.

Operating temps range from −30 to 140 F, and over-current protection is provided by a built-in circuit breaker. Expect a high MTBF of 100,000 hours at 77 F, making the TR75VA005 well-suited for continuous-duty applications in building automation and control systems.
