FAQs
The P48G28T3024CU is designed for wall-mount installation with a sizable footprint (40.01 in height, 32.63 in width, 13.62 in depth) and a weight of 652 lb. Its NEMA 3R enclosure supports indoor and outdoor semi-protected locations. Field-term wiring uses the M48G1L connection, aiding straightforward terminations and tidy panel layouts. This combination supports compact, scalable installations in space-constrained control rooms.
The unit delivers 30 kVA at 60 Hz, with a primary voltage of 480 V and a secondary voltage of 208Y/120 V across three phases. Copper windings with 180 °C insulation and a 115 °C rise specify thermal robustness, while a 3R enclosure and sound rating NEMA ST-20 ensure reliable operation in typical plant environments.
Yes, it supports outdoor or semi-outdoor spaces via its NEMA 3R enclosure, designed for protection against rain and minimal weather exposure. While Eaton notes that a Weather shield is not required for this model, proper installation practices and site conditions should still be observed to maximize reliability.
This Mini-Power center is UL Listed, CSA Certified, and IEEE Certified, with ANSI standards compliance. These certifications confirm safety, reliability, and interoperability across international facilities, simplifying procurement and regulatory approvals for industrial and data-center environments.
Warranty terms follow Eaton’s policy 25-000: one year from the date of installation or eighteen months from shipment, whichever occurs first. This provides coverage for manufacturing defects and early-life performance, supporting maintenance planning and total cost of ownership considerations.
