1.
⁄Ω¡§-15A interrupt ratings were measured @ 70%-80% power factor on AC, 18-30A measured @ 85%-95% power factor on AC and at a time constant described in U.L.
198L
2. Voltage drop was measured at 25°C±3°C ambient temperature at rated current.
3. I
2
t was measured at listed interrupting rating and rated voltage.
4. Interrupting rating for ABC
⁄Ω¢
-15A @ 125V is 10000A. Interrupting rating listed corresponds to maximum rated voltage.
