FAQs
NT27M24S1516 is a 1-phase, 15 kVA transformer with a 277 V primary and a 240 V delta secondary. It supports standard industrial panel boards and automation equipment configured for these voltages. The unit uses taps for voltage adjustment (+2.5% / -2.5%), aiding compatibility with minor supply fluctuations. Ensure mounting fits the 18.39 in depth, 22.89 in width, and 31.3 in height footprint, and verify enclosure clearance for 263 lb weight.
The NT27M24S1516 provides two taps at +2.5% and four taps at -2.5%, allowing precise on-site voltage tuning. This capability minimizes under- or over-voltage events during motor starts, load changes, or supply swings, improving control accuracy and reducing thermal stress on downstream devices. Properly configuring taps during commissioning yields measurable improvements in equipment longevity and process stability.
Yes. The transformer features WS11 Weathershield protection and an aluminum coil, designed for rugged environments and outdoor mounting where applicable. Its electrostatic shielding further enhances EMI resilience in exposed locations. When installing outdoors, ensure appropriate enclosure rating and ventilation are maintained, and verify the installation site meets local electrical and ambient temperature requirements to maximize service life.
The NT27M24S1516 is UL Listed and NEMA TP-1 compliant, with DOE 2016 efficiency requirements. These certifications indicate the unit meets safety, reliability, and energy-use standards critical for industrial facilities, OEM equipment, and building automation projects. Compliance simplifies procurement, reduces risk in regulated environments, and supports lower operating costs through improved efficiency.
With a 15 kVA rating and DOE 2016 efficiency, the NT27M24S1516 reduces energy losses and cooling loads, delivering a favorable ROI in steady-state operations.
