Features
300kVA High-Capacity Power Distribution
Three-phase pad-mounted design steps down 12470V Delta primary to 480Y/277V Wye-N secondary, ideal for medium-to-heavy commercial and industrial applications.
Full North American Compliance
UL/cUL certified, fully meeting ANSI/IEEE standards, DOE 2016 efficiency, and NEMA 3R weatherproof requirements for utility-grade safety.
Robust Compartmental-Type Construction
Liquid-filled, dead-front pad-mounted design with radial feed capability, built to withstand harsh outdoor environmental conditions.
Efficient KNAN Self-Cooling
KNAN (Self-Cooled) cooling system eliminates the need for external fans, reducing maintenance costs and operating noise in industrial environments.
Precise Voltage Regulation
5-position tap changer (2.5% tap range) with external operating handle for easy field adjustment, optimizing voltage across varying load conditions.
Superior Surge Protection
Factory-fitted 18kV Class surge arrestors provide reliable protection against lightning strikes and voltage surges in overhead grid systems.
High-Efficiency Copper Windings
High-purity copper windings with Dyn11 vector group guarantee low no-load loss, high efficiency, and stable power transmission.
Reliable Insulation System
Non-PCB mineral oil insulation ensures excellent thermal stability, fire resistance, and long-term service life in demanding outdoor applications.
