Functional Features:
- Digital, solid-state, RMS-sensing trip system
- Interchangeable rating plug allows field adjustment of ampere rating without replacing the breaker
- Adjustable instantaneous with tracking short-time as standard
- Toggle actuator
- Frame only (trip unit and lugs not included in some listings)
Structural Characteristics: The breaker features a robust SK frame with electronic solid-state trip unit. The “A” designation in the model number indicates the presence of an interchangeable Amp Rating Plug, allowing the trip amperage to be changed in the field.
Working Principle: The solid-state trip unit digitally samples the current to determine the RMS value, providing precise LSI protection. The interchangeable rating plug establishes the breaker’s ampere rating, which can be changed by swapping the plug.
Installation Requirements:
- Bolt-on/front mounting style
- Suitable for use with GE panelboards
- Requires separate purchase of trip unit and lugs in “frame only” configuration
- Install by qualified personnel per UL 489 and local electrical codes
Usage Notes: Ideal for main distribution panels and critical branch circuits where high interrupting capacity and digital trip technology are required. The interchangeable rating plug provides flexibility for future load changes.
