Thermal-Magnetic Breaker Ground-Truth Fixtures

Purpose: provide real-world LV thermal-magnetic breaker examples for protection settings page tests. These fixtures intentionally include only data required for protection coordination and arc flash: voltage, ampere rating, interrupting rating, continuous-duty assumption when non-default, thermal setting behavior, magnetic/instantaneous setting behavior, selected settings, and source data needed to identify the manufacturer time-current curve.

Primary source:

Rockwell Automation, Molded Case Circuit Breaker Specifications Technical Data, publication 140G-TD101E-EN-P, August 2025: https://literature.rockwellautomation.com/idc/groups/literature/documents/td/140g-td101_-en-p.pdf

Evidence Contract

Each fixture below should be usable to test that the protection settings page can:

identify the placed device as circuit_breaker_lv
resolve the thermal-magnetic component as the active trip package
display fixed settings as catalog-derived values without requiring user input
display adjustable settings as editable current settings with valid min/max source limits
preserve the selected thermal/magnetic settings in thermal_magnetic_settings
display interrupting rating at the applicable system voltage for arc-flash/fault-duty review
link the device to the correct manufacturer time-current curve figure

For adjustable Rockwell thermal-magnetic units, the source tables publish the minimum and maximum of the possible settings and the count of possible settings. They do not publish every intermediate dial stop in the extracted text. Treat the exact intermediate dial positions as unknown unless they are later digitized from the source figure or another manufacturer table.

Adjustable settings not at maximum:

tm-140g-j0-080-adjustable, tm-140g2-k5-300-adjustable, tm-140g2-l6-500-adjustable

Known Limits

tm-140g-h6-100-adjustable, tm-140g-j0-080-adjustable, and tm-140g2-k5-300-adjustable now have committed digitized seed fixtures in src/lib/protection-library/rockwell-140g-reference.ts, with thermal point-band data and 5x/10x magnetic pickup rows.
The remaining PDF curve figures in this file are source-linked but not yet digitized into sampled catalog_curve_data rows.
The source tables provide min/max and setting count for adjustable thermal and magnetic ranges; exact intermediate dial positions should not be invented.
These examples are ground truth for normalized device/settings behavior and source curve linkage. Numeric TCC interpolation tests for the remaining examples should add digitized point fixtures from the referenced figures before asserting trip time samples.
