Kele tr40va001 Transformer 40 Va 120 to 24V Ac

Product Description

The KELE tr40va001 is a step-down control transformer rated at 40 volt-amperes (VA), converting 120 VAC primary voltage to 24 VAC secondary voltage. This transformer serves as the low-voltage power source for control circuits in HVAC systems, thermostats, zone valves, and building automation equipment. It supports foot mounting and single threaded hub mounting, giving installers two secure options for positioning the unit within a panel or enclosure. Its compact form factor makes it suitable for installations where space inside a control cabinet or electrical enclosure is limited.

The tr40va001 is intended for residential and light commercial applications where a reliable 24 VAC control circuit is required. Typical installations include furnace control boards, air handler low-voltage terminals, hydronic zone control panels, and packaged rooftop unit control wiring. At 40 VA, the transformer handles moderate control-circuit loads including multiple zone valves or a thermostat with accessory terminals. It is installed by licensed HVAC technicians and electricians during new construction, equipment replacement, or control system upgrades.

Key Features

• 40 VA capacity supports moderate low-voltage control circuit loads
• 120 VAC primary to 24 VAC secondary step-down conversion
• Foot mount and single threaded hub mount options for flexible installation
• Compact design suited for space-constrained enclosures and panels
• Built for consistent, reliable power delivery in residential and light commercial systems

Compatibility

Designed as an OEM-style replacement or new-installation control transformer for residential and light commercial HVAC control circuits requiring a 40 VA, 120 to 24 VAC step-down transformer.

Installation Notes

Installation should be performed by a licensed HVAC technician or electrician. Disconnect and lock out all power to the control panel before removing or installing the transformer. Verify that the connected control circuit load does not exceed the 40 VA rating to prevent overheating or nuisance tripping. Wiring should comply with applicable NEC requirements for low-voltage control circuits and any local jurisdictional amendments.
