Features
  • Complete range of UL 489 listed DIN rail mounted miniature circuit breakers up to 40 ampere current rating
  • Standard ratings of 10 kAIC at 277 / 480 Vac
  • Select amperages available at 14 kAIC at 277 / 480 Vac and 10 kAIC at 125 Vdc
  • Current limiting design provides fast short-circuit interruption that reduces the let-through energy, which can damage the circuit
  • Suitable for branch circuit device protection
  • Thermal-magnetic overcurrent protection—— Two levels of short-circuit protection, categorized by C and D curves
  • Trip-free design — breaker can not be defeated by holding the handle in the ON position
  • Captive screws cannot be lost
  • SWD (switching duty) — suitable for switching fluorescent lighting loads (In ≤ 20A)
  • Fulfill UL 489, CSA C22.2 No.5 and also IEC 60947-2 Standard
  • For use in applications for which UL 1077 or CSA C22.2 No.235 are also allowed
  • Field installable shunt trip and auxiliary switch subsequent mounting
  • Separate version for ring-tongue connection (Type WMZT….T), terminal screws can be removed (on both sides)
  • Module width of only 17.7 mm (per pole)
  • Contact Position Indicator (red / green)
  • Easy installation on DIN rail
  • Possibility for sealing the toggle in ON or OFF position
