Square D by Schneider Electric 9070TF100D1 Control Transformer

Square D by Schneider Electric 9070TF100D1 is a Type TF, single‑phase industrial control transformer rated at 100 VA (0.1 kVA). It accepts a primary voltage range of 240 to 480 VAC and provides a 120 VAC secondary, making it suitable for powering control circuits in machines, control panels, relays, contactors, and timer modules. The unit operates at 50/60 Hz and is designed specifically for 1‑phase systems with a 240/480 V primary to 120 V secondary configuration. As part of Schneider Electric’s Square D 9070 family, this transformer supplies low‑voltage power for control devices in electrical panels and motor control centers. Typical applications include powering coil circuits for contactors and relays, timer inputs, and other control components in industrial automation. The 9070TF100D1 designation denotes a 1‑phase, 100 VA transformer, matching common control‑power needs where 240/480 V supply is stepped down to 120 V for control circuitry.
