Product questions
Does the MO165-20 provide motor overload protection?
No. The MO165-20 is magnetic-only and provides short-circuit protection, not thermal overload protection. An appropriately selected separate overload relay or motor controller is needed for motor overload protection.
What are the MO165-20 current and magnetic trip ratings?
Its rated operational current is 20 A, and its instantaneous short-circuit release setting is 300 A. The 300 A setting is not the normal operating current.
What motor power and breaking capacity are specified at 400 V AC?
For AC-3 duty at 400 V, the MO165-20 is rated 7.5 kW. Its rated service short-circuit breaking capacity at 400 V AC is 100 kA. Check the motor nameplate and available fault current before selection.
Can the MO165-20 be used on single-phase and three-phase circuits?
ABB describes the three-pole MO165 as suitable for both single-phase and three-phase applications. Suitability for a particular installation still depends on its electrical ratings and circuit design; provide the equipment model and serial number for verification.
