Copeland Comfort Control (White Rodgers) 90-T50C3 Transformer

The Copeland Comfort Control (White Rodgers) 90-T50C3 Transformer is a heavy-duty, 50VA power solution designed for industrial, heating, and air conditioning control circuits. This multi-tap transformer features primary voltage inputs of 120V, 208V, and 240V, providing professional versatility for various field applications. The secondary output delivers a consistent 24VAC at 2.08 Amps, essential for powering thermostats, contactors, and integrated furnace boards. Built with open construction and color-coded primary leads (11-inch length), it simplifies wiring in tight cabinets. A critical feature for technicians is the integral manual reset circuit breaker, which protects the secondary circuit from overloads and short circuits without the need for traditional fusing. This foot-mount transformer is a reliable Class 2 electrical component, commonly used as a direct replacement for JARD 5041C and MARS 50327 models, ensuring high performance in demanding HVACR environments.

• Triple Primary Voltages: Supports 120/208/240V AC inputs, reducing the number of individual truck stock parts required.
• Manual Reset Protection: Features a built-in breaker to safeguard equipment against downstream shorts and over-current conditions.
• High VA Rating: The 50VA capacity allows for multiple accessories and heavy-duty contactor coils to be powered simultaneously.
• Compact Foot Mount: Standardized mounting footprint ensures compatibility with most existing furnace and air handler chassis.
• Simplified Wiring: Includes 11-inch color-coded leads for rapid identification and secure primary electrical connection.

Is the 90-T50C3 a suitable replacement for a 40VA transformer?
Yes, moving from a 40VA to a 50VA rating is acceptable as it provides 25% more power capacity for the 24V secondary circuit, as long as the primary voltages and mounting dimensions match.

What does the manual reset button do?
The manual reset acts as a circuit breaker. If the transformer detects an electrical overload, it trips to prevent internal damage; once the fault is cleared, the technician can manually reset the unit to restore power.

Can this transformer be used for both 50Hz and 60Hz systems?
Yes, this White Rodgers control transformer is rated for both 50Hz and 60Hz operation, making it compatible with various international and domestic power standards.
