Feature → Business Impact → Application: The NT20P11S3716 employs a K-Factor nonlinear design and electrostatic shielding to reduce harmonics and heat, improving equipment life and uptime in critical panels. This translates to lower maintenance costs and higher process reliability in packaging lines and machine controls. The single-phase, 37.5 kVA rating supports mid-size loads with compact footprint, enabling easier room planning and faster panel integration for OEMs and maintenance teams. The 240/480 V primary and 120/240 V secondary voltages offer versatile wiring options, reducing the need for multiple transformers on site and accelerating installation in control cabinets. DOE 2016 efficiency and UL Listed certification remove compliance bottlenecks, while a NEMA 2 enclosure enhances protection in standard shop environments. With aluminum windings and a 150°C rise, you gain durable performance under demanding industrial conditions, supporting long service intervals and predictable ROI.
