I´m looking for a three pole 120/240 rated m.c.c.b ( plug-in or cable-in/cable-out type) UL-489 certified in order to be used in a three phase 208Y/120 volts power system as main protection or feeder.

I´ve seen some products manufactured by Westinghouse/cutler-hammer but rated 240 (called "quick-lag").

Would you please inform me if you know any reference and manufacturer?
