Automatic two-phase
circuit breakers AP50B-2MT
|
AP 50B-2MT is a family of automatic circuit breakers that are
designed for overload and short-circuit protection in electric circuits with voltages
of up to 220 V DC and up to 500 V AC 50-60 Hz. They are also designed for routine
on and off switching of these circuits, 6 to 30 times per day, including electric
motor starts, protection and shutdowns.
