SN4 Industrial Combination and Non-Combo Starters

  • Damp, wet, dirty, dusty areas where ultimate corrosion and ingress protection is required
  • Harsh motor control environments, including: refineries, chemical and petrochemical plants, corrosive process facilities, food and beverage, marine and mining
  • Across-the-line starting, stopping, speed changing and reversing of polyphased AC induction motors
  • Available with solid-state electronic overload providing reliable, accurate and value-driven protection, including communication capabilities, while reducing inventory carrying costs with wide FLA adjustment (5:1) and selectable trip class. And Bi Metallic Thermal overloads.
  • Adjustable bimetallic ambient compensated overload relays with interchangeable heater packs – available in three basic sizes, covering applications up to 600 HP
  • Fixed heater overloads optional
  • A full line of snap-on accessories – top and side mounted auxiliary contacts, solid-state and pneumatic timers
  • Straight through wiring – line lugs at top, load lugs at bottom
  • Horizontal or vertical mounting on upright panel for application freedom
  • Screw type power terminals have captive, backed-out selflifting pressure plates with ± screws for reduced wiring time
  • Accessible terminals for easy wiring; optional fingerproof shields available to prevent electrical shock
  • Top located coil terminals convenient and readily accessible.
  • 45 mm contactor magnet coils have three terminals, permitting either top or diagonal wiring – easy to replace European or U.S. style starters or contactors without changing wiring layout
