Rectorseal MARS-50354 Foot Mount Transformer 40VA 24V

Product Description

The RECTORSEAL MARS-50354 is a compact, open-construction control transformer designed for low-voltage HVAC control circuits. It steps down primary voltages of 120, 208, or 240 volts to a 24-volt secondary output at a 40 VA rating, covering the control power demands of most residential and light commercial heating and cooling systems. Standing less than 2.25 inches in height, the unit is built for tight equipment enclosures where clearance is limited. The foot-mount configuration allows direct attachment to a panel, bracket, or equipment chassis without additional hardware. HVAC technicians install this transformer as a direct replacement in existing equipment or as part of a new control circuit build.

This transformer is suited for residential and light commercial HVAC applications where a reliable 24-volt control circuit is required. The multi-tap primary accommodates common North American supply voltages, making it adaptable across a range of installed equipment without sourcing separate units for different voltage configurations. It is a practical field replacement when the original control transformer fails or when upgrading an aging control circuit during a system service call.

Key Features

• Multi-tap primary accepts 120, 208, or 240 volt input for broad voltage compatibility
• 24-volt secondary output at 40 VA suits standard HVAC control circuit loads
• Open construction, compact design at less than 2.25 inches in height
• Foot-mount configuration for direct panel or chassis attachment
• Built as an OEM-style replacement for existing equipment installations

Compatibility

Designed as an OEM-style replacement control transformer for residential and light commercial HVAC systems requiring a 24-volt, 40 VA control circuit with 120, 208, or 240 volt primary input.

Installation Notes

Control transformers are installed by licensed HVAC technicians or qualified electricians. De-energize and lock out the equipment at the disconnect before removing or installing the transformer. Verify primary voltage at the supply before making connections, and confirm the correct primary tap is selected to match the supply voltage. Follow NEC requirements for low-voltage control wiring and transformer installation within equipment enclosures.
