Product questions
Does the ABB MO165-65 provide motor overload protection?
No. The MO165-65 provides magnetic short-circuit protection only. An appropriately selected thermal or electronic overload relay is needed for motor overload protection.
What are the current and short-circuit ratings of the MO165-65?
Its rated operational current is 65 A and its instantaneous short-circuit current setting is 975 A. At 400 V AC, the rated service breaking capacity Ics is 30 kA; the rated ultimate breaking capacity Icu is 50 kA. Check the fault level and applicable installation requirements before selection.
Can the MO165-65 be used with a 30 kW motor at 400 V?
ABB lists the MO165-65 at 30 kW for three-phase AC-3 operation at 400 V. This rating alone does not establish suitability: check the motor nameplate current, starting conditions, short-circuit level and overload protection for the installation.
What are the MO165-65 dimensions and mounting options?
The unit measures 55 mm wide, 142.65 mm high and 122.1 mm deep. It can mount on a TH35-7.5 or TH35-15 DIN rail and has screw terminals. Allow appropriate space for installation.
