**Approvals: UL Recognition, Std. 248-14, Guide #JDYX2, File #E19180; CSA Certification, C22.2 No. 248.14, Class #1422-01, File #53787.
1. Interrupting ratings were measured at 100% power factor on AC, and a time constant less than 1ms on DC.
2. Voltage drop was measured at 25°C ± 3°C ambient temperature at rated current with device mounted on a circuit trace.
3. I
4. Electrical characteristics for 12.5 amp to be determined.
5. Device designed to carry 125% of rated current for one hour minimum. An operating current of 80% or less of rated current is recommended, with further derating
