Schneider Electric SE 5S1F Dry Type Transformer

Schneider Electric’s Square D 5S1F dry-type transformer is a compact, encapsulated 5 kVA single-phase unit that steps from a 240 × 480 V primary to a 120/240 V secondary. Built as a dry-type, encapsulated transformer, it provides galvanic isolation and clean, low-impedance power for control panels, machine circuits, and low-voltage distribution in industrial or commercial applications. The 5S1F model carries a 13B insulation class and a 115°C rise rating under Trade Agreements Act (TAA) conditions, and is designed for reliable operation within typical room temperatures. Weighing about 115 lb (approximately 52 kg) with a simple, no-tap configuration, it delivers 5 kVA of power in a compact footprint suitable for panel upgrades and space-constrained installations. This transformer is part of Schneider Electric’s Square D dry-type family, known for predictable performance and straightforward integration into low-voltage distribution schemes, providing a safe, isolated source of 120/240 V for control circuits and lighting or small equipment fed from a 240/480 V supply.
