The Delta DC6300V is a 300 KVA, 600V → 120/208V three-phase step-down transformer, purpose-built for industrial and commercial power distribution where a 600 V primary feed must be converted to a usable 120/208 V secondary for equipment and lighting loads. Its NEMA 3R rainproof enclosure makes it equally suited for outdoor pad-mount installations, rooftop mechanical rooms, and covered service entrances across Canada's varied climates. At 300 KVA, this unit comfortably supports large commercial buildings, industrial process loads, and multi-tenant distribution panels. Not sure whether 300 KVA is the right size for your load schedule, or need to confirm outdoor siting requirements? Contact our team and we'll help you verify.
Yes. The NEMA 3R enclosure is rated for outdoor use and provides protection against rain, sleet, and windblown debris, making it well suited for Canadian outdoor installations — including rooftop, pad-mount, and covered-entry applications. For installations subject to extreme cold or salt-air environments (e.g., coastal BC or northern Alberta), confirm with our team that no additional weatherproofing is required for your specific site.
A general rule of thumb is to total your connected load in amps on the 120/208 V secondary, apply a demand factor, and verify the resulting KVA falls below 300 KVA with an appropriate safety margin (typically 80% continuous loading). For three-phase 208 V loads: KVA = (√3 × 208 V × full-load amps) ÷ 1,000. Our application specialists can review your load schedule and confirm whether the DC6300V — or an adjacent KVA rating — is the best fit.
In most cases, yes — provided the KVA rating, primary/secondary voltages (600 V → 120/208 V), phase configuration, and physical footprint are compatible with your existing installation. Because transformer dimensions and connection configurations can vary between brands, we recommend sending us your existing unit's nameplate details or drawings so we can confirm a direct fit before you order.
