  • Construction Features: HACR rated; non-interchangeable trip; reverse feed capable; quick-make/quick-break mechanism; trip-free mechanism; molded case constructed from high mechanical and dielectric strength engineered plastic; silver alloy contacts; arc chutes with heat-absorbing insulating material and metal grid plates.
  • Applications: Commercial and light-industrial power distribution; suitable for GE A-Series and GE Spectra Series panelboards; HACR applications.
  • Installation Requirements: Bolt-on mounting into compatible GE panelboards; use proper lug kits (e.g., TCAL15); follow torque specifications for lug terminals; verify wire gauge compatibility (3 AWG min to 3/0 AWG max).
  • Usage Notes: The breaker is non-interchangeable trip—do not attempt to change trip elements in the field; reverse feed is permitted; handle position midway between ON and OFF indicates a trip condition, requiring a full OFF-to-ON reset sequence.
