Square D 9070EO81D1 Control Transformer 1.5 KVA HI

Square D 9070EO81D1 is a 1.5 kVA, single‑phase control transformer from Square D (Schneider Electric) in the EO family. It accepts a 240/480 VAC primary and provides a 120 VAC control secondary, making it a compact source for control circuits in industrial panels and equipment. This open‑frame transformer is rated for 60 Hz operation (50 Hz variants exist within the EO line) and delivers up to 1,500 VA for powering a range of control devices from a higher‑voltage supply. The EO81D1 designation identifies a specific EO configuration commonly used in panel installations to isolate the control circuit from main power. With its open construction, it can be mounted inside control panels where access for wiring and airflow is important. Typical applications include machine controls, panel assemblies, and other industrial automation installations that require reliable 120 VAC control power derived from a 240/480 VAC source. When integrating this transformer, verify the correct voltage code and terminal connections for your installation to ensure proper isolation and safe operation in accordance with applicable electrical standards.
