† NOTE: SFT 12.5A is UL recognized on AC Only.
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. I2t measured at 50 amp, 125 VAC, .95PF, random closing angle; 300 amps, 125 VDC, TC<1ms.
4. Device designed to carry 100% of rated current for four hours minimum. An operating current of 80% or less of rated current is recommended, with further derating
required at elevated ambient temperatures.
