Description
The Functional Devices TR40VA003 is a dependable 40VA isolation transformer engineered for HVAC control circuits and building automation applications. With a 24Vac primary and 24Vac secondary voltage configuration, this unit is purpose-built to power low-voltage control systems reliably and safely.
Inherently Limited Overcurrent Protection
The TR40VA003 features inherently limited overcurrent protection, meaning the transformer is designed to self-limit fault current without the need for an external fuse or breaker on the secondary side. This built-in safety characteristic simplifies installation and reduces component count while maintaining full compliance with industry standards.
Versatile Mounting Options
Designed for flexible field installation, this transformer supports both foot mount and single threaded hub mount configurations, making it easy to install in electrical enclosures, junction boxes, or directly on conduit.
