Selling Policy 25-000 - Distribution and Control Products and Services
The K-Factor nonlinear design and hardened insulation of the N48M47T30A are engineered to handle harmonic-rich loads common in modern plants. Business impact: This reduces overheating risk, extends insulation life, and lowers maintenance costs when drives and PWM equipment dominate the load profile. Application: Ideal for industrial power distribution in automation lines, robotics cells, and packaging facilities where clean power delivery and minimal downtime matter. Ventilated construction with aluminum windings and an electrostatic shield improves cooling efficiency and EMI suppression. Business impact: Better heat dissipation translates to higher continuous duty capability and tighter EMC performance within compact control cabinets. Application: Particularly beneficial in motor drive environments, servo systems, and high-density control panels where space, heat, and interference are critical. Tap settings include 2 at +2.5% FCAN and 4 at -2.5% FCBN, enabling precise voltage regulation under network swings. Business impact: Operators can maintain stable voltage to PLCs and instrumentation, reducing nuisance trips and equipment stress. Application: Useful for facilities with variable loads, long feeder runs, or inconsistent utility supply. Primary 480 V, secondary 480Y/277 V, 60 Hz, three-phase, 30 kVA rating, 150°C rise. Business impact: This configuration matches standard plant infrastructure and enables compatibility with typical switchgear and panel boards while supporting high ambient operation. Application: Suitable for distribution on manufacturing floors, data centers with critical loads, and industrial automation centers. Rugged frame 912B and WS38 weather shield provide installation flexibility for indoor, outdoor, or harsh environments. Business impact: Enables outdoor mounting and easier retrofits without additional enclosures, lowering total installed cost. Application: Ideal for facilities with exposed spaces, outdoor equipment yards, or operations in hot or dusty environments.
