FAQs
Begin by confirming space for a 30 kVA, single-phase transformer and ensure the enclosure supports a 24.22 in width, 42.03 in height, and 23.84 in depth. Mount on a level base, connect the 208 V primary to the designated input feeders, and wire the 120/240 V secondary to the load side. Verify cooling paths, use the correct taps for voltage conditions, and observe the NEMA TP-1 and UL listings during commissioning.
The transformer is designed with a 208 V primary and dual secondary outputs of 120/240 V, supporting single-phase systems with broad compatibility across control panels and automation equipment. Its K-Factor nonlinear design handles harmonic content, while the 60 Hz rating aligns with most industrial power systems, enabling stable voltage delivery and reliable performance under typical plant loads.
The unit provides 2 taps at +2.5% and 4 taps at -2.5%, allowing fine-tuned voltage adjustment to compensate for line drop and load changes. This enhances output stability, reduces equipment stress, and minimizes downtime from voltage fluctuations, which is especially beneficial for sensitive PLCs and motor control centers in dynamic production environments.
NT29M11S3016 is UL Listed and NEMA TP-1 compliant, ensuring compliance with safety and performance standards. It also aligns with DOE 2016 Efficient standards, promoting energy efficiency in operation. Additional features include electrostatic shielding and WS16 weather protection for installations in challenging environments, supporting long-term reliability.
The 30 kVA transformer reduces energy waste through DOE 2016 efficiency compliance and improves uptime by stabilizing voltage, lowering thermal stress on downstream equipment. Its aluminum coil and robust frame simplify maintenance and installation, while UL and NEMA TP-1 certifications minimize regulatory risk. Overall, you can expect lower cooling costs, fewer voltage-related faults, and longer service life.
