Designed for use in thermostats, relays, contactors, and other low-voltage control components, this compact transformer supports residential and light commercial heating and cooling systems. The Class II design limits output energy for NEC-compliant safety and protects downstream components from overload or short circuit. Featuring a standard foot-mount base and wire lead connections, this class 2 transformer installs easily in control panels, furnace cabinets, or electrical enclosures. Mounting holes are spaced 2.756 in. (70 mm.) apart for compatibility with a wide range of HVAC equipment. Built to replace transformers with equal or lower VA ratings, this 40VA foot mount transformer is a dependable solution for maintenance, upgrades, or OEM replacements in air handlers, heat pumps, and air conditioners.
