This Eaton Motor Protection Circuit Breaker (MPCB) is designed for industrial applications to protect three-phase motors up to 1.5 kW against overloads and short circuits. Its pre-assembled, IP65-rated enclosure simplifies installation, offering robust protection. A key benefit is its adjustable current setting, allowing precise motor matching. However, it lacks an integrated auxiliary switch, requiring external wiring for signaling functions.

This breaker is designed for motor loads up to 1.5 kW at 440V.
No, this is a 3-pole motor protection circuit breaker designed specifically for three-phase AC motor loads.
IP65 indicates that the enclosure is dust-tight and protected against water jets from any direction, making it suitable for harsh environments.
The current setting is adjusted using the rotary knob on the front of the breaker, typically calibrated from 1.6 A to 2.5 A.
No, this specific model (PKZM01-2,5-G) does not have an integrated auxiliary switch. Auxiliary contacts would need to be added separately if required.
The rated short-circuit breaking capacity (Icu) is 50 kA at 400 V AC.
Yes, after an overload or short-circuit trip, a manual reset using the push-button is required.
Check if the overload setting (1.6-2.5 A) is too low for the motor's startup current. Increase the setting if the motor's actual full load current is higher. Verify the motor is not jammed or under excessive load.
The overload setting may be too close to the motor's full load current, or the motor may be drawing excessive current due to overheating, voltage imbalance, or mechanical issues. Verify the setting and motor condition.
Ensure the cause of the trip (overload or short circuit) has been resolved. Some models require a brief cool-down period after an overload trip. Check for any mechanical obstruction preventing the reset button from engaging.
Verify power supply to the breaker is present and correct phase sequence is maintained. Check internal connections and ensure the motor itself is functional. The breaker may have failed internally, though this is rare.
