FAQs
The transformer is three-phase with a 416 V primary and 208Y/120 V secondary. Plan for a ventilated, accessible location with adequate clearance and a solid mounting base to support its 3000 lb weight. Use the tap settings (+2.5% and -2.5%) to regulate voltage under load, ensure proper wiring to 50/60 Hz supplies, and provide appropriate overcurrent protection and shielded copper conductors.
K-Factor nonlinear design targets harmonic currents produced by modern drives and loads, reducing waveform distortion and heat buildup. This results in lower plate and insulation stress, improved efficiency, and longer equipment life. In practical terms, expect more stable bus voltages, reduced cooling requirements, and fewer unplanned outages in automation labs and production lines.
Yes. With 300 kVA capacity, three-phase operation, and a 416 V to 208Y/120 V output, the N43M28B33XCSCU is well-muited for machine control panels and distribution boards. The copper windings offer low impedance, aiding voltage regulation for sensitive drives, PLCs, and sensors. Its UL Listed status supports compliance in regulated manufacturing environments and simplifies procurement.
This model is UL Listed, providing recognized safety certification for industrial electrical equipment. While UL Listed handles safety compliance, verify site-specific requirements for CE marking or IP ratings if applicable to your region or enclosure standards. The combination of UL safety certification and rugged design supports reliable operation in harsh manufacturing environments.
The transformer’s high efficiency, reduced thermal stress from the ventilated design, and robust copper windings contribute to lower energy losses and cooler operation. The 80°C rise rating enables greater loading density, potentially reducing footprint and cost. Over time, reliable voltage regulation and harmonics management translate to decreased downtime, reduced maintenance, and improved productivity in automated production lines.
