FAQs
For outdoor or semi-exposed installations, select a location with appropriate ventilation and clearance per enclosure guidelines. The S48G11S26X uses a NEMA 3R enclosure and is rated for indoor-outdoor duty, so ensure panel mounting allows access for wiring via the 2D connection while maintaining protection from moisture and dust. Use proper sealants on entry points to preserve integrity.
Key specs include a 0.25 kVA rating, primary 480 V, secondary 120/240 V, 50–60 Hz, single-phase, and 2 at -5% FCBN taps. These values inform transformer sizing for relays and PLCs, influence wire sizing and overcurrent protection, and guide layout to minimize voltage drop and thermal buildup in compact control panels.
Yes. The S48G11S26X is UL Listed and ships with a NEMA 3R enclosure suitable for indoor-outdoor use. This combination supports regulatory compliance for safety and reliability in diverse environments, reducing vendor risk and simplifying procurement for regulated facilities.
Ideal for control panels, machine automation, and small power circuits within industrial automation. Its 0.25 kVA rating and 480 V to 120/240 V secondary supply are well-suited for powering relays, timers, and control logic in compact cabinet configurations, while the rugged enclosure supports outdoor or harsh environments.
The compact footprint and aluminum coil reduce weight and installation time, while the NEMA 3R enclosure minimizes weather-related maintenance. UL Listing and a robust build lower procurement risk and field service frequency, contributing to lower total cost of ownership and improved system uptime in automation deployments.
