Schneider Electric 250SV1B Control Transformer

Schneider Electric's Square D 250SV1B is a dry-type, encapsulated general-purpose transformer rated at 0.25 kVA that steps 240/480 VAC primary input down to 120/240 VAC secondary output. This single-phase unit is designed for wall mounting and comes in a NEMA 3R enclosure suitable for outdoor use or rugged indoor installations. It is specified for 60 Hz operation with a 55°C rise (TA A) and has a compact footprint of about 5.23 in W × 4.06 in D × 5.5 in H, weighing roughly 10.5 lb. This 0.25 kVA transformer provides 120 V and 240 V secondary outputs from a 240/480 V primary, making it a common choice for control circuits and equipment that require 120/240 V derived from higher-voltage distribution.
