Protection decisions with the ratings visible

GE circuit breaker selection for real panel conditions

Match system voltage, continuous current, poles, trip curve, available fault current, interrupting capacity and mounting interface before approving a replacement or new feeder device. Our project desk keeps the known ratings, open checks and requested documentation together from inquiry through quotation.

Grouped selection record

Start with the electrical duty, then prove the interface

Review groupRequired inputsWhy it matters
SystemRated voltage, frequency, phase and grounding arrangementDefines the insulation and application boundary.
ProtectionContinuous current, load type, trip curve and selective coordination objectiveSeparates conductor protection from nuisance-trip risk.
Fault dutyAvailable fault current and required interrupting capacity or SCCRA breaker rating must meet the installation duty under applicable rules.
MechanicalFrame, poles, mounting, terminal orientation and enclosure clearanceAn electrically similar breaker is not automatically a physical replacement.

Published example ranges are screening references, not a claim that every catalog number covers every value. Final ratings, listings and accessories must be verified on the exact series documentation.

Application context

Protection priorities change with the distribution system

01

Panel builders

Confirm feeder duty, bus SCCR, wire range, accessory voltage and enclosure space before releasing drawings.

02

Commercial facilities

Balance maintainability, selective coordination and arc-flash objectives across service and branch equipment.

03

OEM machinery

Review motor loads, control power, destination standards and replacement access inside compact control panels.

04

Water and process plants

Account for motor starting, humid environments, downtime constraints and documented lockout practices.

Bring the panel evidence

Build a circuit breaker request that engineering can review

Send the existing catalog number, readable label photo, single-line diagram, system voltage, load current, available fault current, poles, mounting style, accessory requirements, quantity and destination. Unknown values can remain marked as unknown so the next measurement or document request is explicit.

  • Series-level trip curves, drawings and listing documents
  • Quote, availability and delivery coordination
