Schneider Electric S30021-715-60 Control Transformer

Schneider Electric's S30021-715-60 is a Class 9070 industrial control transformer that delivers 70 VA of isolated low-voltage power for control circuits inside electrical panels and control cabinets, enabling reliable supply to relays, contactors, PLCs, and other control devices from the main power line while providing galvanic isolation between primary and secondary. As part of the Square D/SCHNEIDER Electric 9070 family, the S30021-715-60 is designed for dual-frequency service, rated for both 50 Hz and 60 Hz, supporting operation in facilities that run on either standard. The transformer is commonly used in automation applications where a dedicated control power source is needed in machine controls, panelboards, and control desks, helping to simplify wiring and improve panel organization. With its 70 VA rating, it delivers adequate secondary power for moderate-load control circuits while maintaining isolation and safety in industrial environments.
