1. Interrupting ratings were measured at 70% - 80% 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

t was measured at listed interrupting rating and rated voltage.

4. Interrupting rating for MDL ⁄Ω¡§-8A @ 125 Vac is 10,000A. Interrupting rating listed corresponds to maximum rated voltage.

5. Other available sizes include ⁄Ω¡ºº, ⁄Ω£™, ⁄ﬁΩ¡ºº, ⁄‡ﬁΩ¡ºº, ›Ω¡º, ﬂΩ¡º, ‡Ω¡º, °Ω¡º, 1¤Ω¡º, 1ﬂΩ¡º, 1°Ω¡º, 2°Ω¡º, 3¤Ω¡º, 3⁄Ω™, 6⁄Ω¢, 7⁄Ω™, 12 and 17⁄Ω™.
