Rectorseal m44513 Class 2 Transformer 75 Va 24V with Circuit Breaker

Product Description

The RECTORSEAL m44513 is a Class 2 foot-mount control transformer with an integrated circuit breaker, designed for low-voltage control circuits in HVAC and building automation applications. It accepts a primary voltage of 120, 208, 240, or 480 volts and steps down to a 24-volt secondary output at 75 VA. The foot-mount configuration allows secure panel or equipment-frame installation. Licensed HVAC technicians and controls electricians are the typical installers. The built-in circuit breaker eliminates the need for a separate secondary fuse, reducing component count and simplifying wiring at the control board.

This transformer is suited for residential and light commercial HVAC systems where a reliable 24-volt control circuit is required. Common applications include gas furnaces, air handlers, rooftop units, and hydronic control panels that require a Class 2 power source per NEC Article 725. The multi-tap primary lets a single unit serve installations with varying line voltages, making it a practical stocking item for service techs working across different sites and voltage configurations.

Key Features

• Multi-tap primary accepts 120, 208, 240, or 480 volt input for broad site compatibility
• 24-volt secondary output at 75 VA meets standard HVAC control circuit demands
• Integrated circuit breaker provides secondary overcurrent protection without a separate fuse holder
• Foot-mount design allows secure attachment to equipment frames or control panels
• Dual-frequency rated at 50 and 60 Hz for domestic and export applications
• Class 2 output rating complies with NEC Article 725 low-voltage control circuit requirements

Compatibility

Designed as an OEM-style replacement or upgrade transformer for residential and light commercial HVAC control circuits requiring a Class 2, 24-volt, 75 VA power source with a multi-tap primary.

Installation Notes

Installation should be performed by a licensed electrician or HVAC technician in accordance with NEC Article 725 and applicable local codes. Disconnect and lock out all primary power before handling any wiring connections. Select the correct primary tap for the available line voltage before energizing, and verify secondary output voltage with a meter prior to connecting the control circuit. Do not exceed the 75 VA secondary load rating.
