RIB TR50VA005 Transformer

The Functional Devices TR50VA005 Transformer is a 50 VA control transformer with a 120 VAC primary and a 24 VAC secondary, designed to power low-voltage loads in control panels and other 24 VAC circuits. It delivers up to about 2.08 A on the secondary and includes an integral circuit breaker for overcurrent protection, meeting Class II requirements and UL/cUL listings for safety. Installation options include foot mounting and a single-threaded hub mount to fit compact enclosures, with primary input wired for 120 VAC and secondary output at 24 VAC. This model is widely cataloged as TR50VA005 (and TR50VA005US in some listings) from Functional Devices, and is sometimes shown in catalogs as RIB TR50VA005 due to distributor naming. The transformer is suited for energizing relay coils, sensors, and other small 24 VAC devices in electrical panels, HVAC controls, and related control-system applications.
