Schneider Electric 15S5H Single-Phase Insulated Transformer

Schneider Electric's Square D 15S5HNV is a dry-type, single-phase transformer rated for 15 kVA, converting a 600 V primary to a 120/240 V center-tapped secondary. As an insulated, oil-free transformer, it is designed for indoor panel and equipment installations, delivering a compact, maintenance-friendly solution where a robust split-phase supply is needed from a higher-voltage source. The 15 kVA rating means a maximum secondary current of about 125 A at 120 V (or about 62.5 A at 240 V), making it suitable for control circuits, machinery, and automation panels that require reliable, dual-voltage output. This unit is part of Schneider Electric's Square D family of power transformers and is intended for applications such as switchgear assemblies, machine controls, HVAC control circuits, and other industrial loads that benefit from a safe, isolated secondary voltage. With its dry-type construction, it provides a low-maintenance alternative to liquid-filled transformers, without compromise on voltage transformation accuracy or load reliability in typical commercial and light-industrial environments.
