Schneider Electric 9070T500D4 Control Transformer

Square D by Schneider Electric 9070T500D4 is a Type T industrial control transformer rated for 500 VA, designed for single-phase operation with a 277 V AC primary and a 120 V AC secondary. This foot-mounted unit ships with 24-inch pre-wired primary and secondary leads for quick panel integration, and it supports 50/60 Hz input with a 115°C rise rating, making it suitable for control circuits and automation equipment that require a stable 120 V control supply from a 277 V source. The 500 VA rating drives moderate loads such as relays and contactors in industrial control panels, while the compact 277→120 V configuration helps conserve enclosure space in typical applications ranging from manufacturing equipment to process automation. Typical installations include motor controllers, relays, contactors, and other 120 V control devices within industrial panels or HVAC equipment that operate off a 277 V supply, where a reliable 120 V control power from a 277 V source simplifies wiring and inventory.
