G-TWI 25/100
This record freezes the 25 A / 100 V rating point of the Gold Twitter family from the official product page, which publishes numeric model-level tables without a form gate. Continuous current is carried in both amplitude and RMS forms as published, and the peak rating is recorded exactly as the published 2 × Ic multiple because no duration is stated on the cited page.

1 bounded physical-evidence record.
Publisher independence, identity precision and measurement scope vary by row. Results remain bounded by the disclosed specimen, setup, workload and metric; an inconclusive mapping is evidence associated with the catalog model, not verification of a manufacturer claim.

Known limits
What this record does not prove.
- Continuous and peak currents are published without ambient, heatsink or duration conditions on the cited page; the customer host board and heatsink govern real thermal capability.
- EtherCAT and CANopen versions are distinct hardware variants with different heights and masses; this record does not select one.
- No RCI physical current, thermal, network-timing or safety test exists.
