Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: K-Factor nonlinear design reduces harmonic currents, improving power quality and protecting sensitive equipment in distribution panels; in practice, this means fewer nuisance trips and longer component life in manufacturing lines and control cabinets. Application: industrial control rooms and machine cells benefit from cleaner power, enabling tighter tolerances and higher uptime. Feature → Business Impact → Application: Ventilated construction enhances cooling, lowering operating temperature rise and enabling sustained 60 Hz operation in warm environments; this translates to safer installations in warehouses and process lines. Application: hotter facilities and spaces with limited ambient cooling gain reliability and lower cooling costs. Feature → Business Impact → Application: 15 kVA single‑phase rating with 240/480 V primary and 120/240 V secondary supports compact transformer sizing in enclosed panels; installation is straightforward in retrofit projects and new builds. Application: panel upgrades for HVAC, dye‑house controllers, and packaging lines. Feature → Business Impact → Application: Aluminum coil and robust frame 816 deliver lightweight durability and corrosion resistance, reducing handling time and maintenance needs; ideal for field installations and serviceable assets. Application: outdoor or semi‑enclosed installations with WS11 weather shielding. Feature → Business Impact → Application: Tap settings maintain voltage flexibility with +5/−5% primary taps and +2.5/−2.5% secondary taps, preserving voltage regulation under load swings; this minimizes equipment stress and improves performance. Application: critical automation panels and motor drives with fluctuating supply voltages. Feature → Business Impact → Application: UL Listed, NEMA TP‑1 compliant, and NEMA TP‑1 efficient catalog notes provide regulatory alignment and confidence for procurement and commissioning; reduces supplier risk and accelerates approvals. Application: regulated industries and projects with strict compliance requirements.
