EATON PKZM0-0.16 Motor Protection Circuit Breaker, 0.16 A, 3-Pole, Rotary Knob, Thermal-Magnetic, DIN Rail 072730

The EATON PKZM0-0.16 motor protection circuit breaker delivers precise thermal-magnetic protection for motors with rated operational currents up to 0.16 A. Its compact PKZM0 frame size and rotary knob actuation ensure straightforward installation and operation in industrial control panels. With a short-circuit breaking capacity of 50 kA at 400 V AC, this device safeguards motors and installations against overloads and short circuits, meeting IEC/EN 60947-4-1 standards.

Advantages

The PKZM0-0.16 offers reliable protection with an adjustable thermal overload release range of 0.10–0.16 A and a fixed magnetic release at approximately 14 times the rated current. Its 3-pole design and screw terminals support secure wiring, while the DIN rail mounting (EN 60715) simplifies installation. The front of the device, when installed in an enclosure, achieves IP65 protection, making it suitable for demanding environments. The rotary knob provides clear visual status indication and easy manual operation.

Recommendations

For optimal motor protection, pair the PKZM0-0.16 with EATON auxiliary contact modules (e.g., NHI-E-10-PKZ0) to enable remote status signaling. Ensure proper sizing by verifying the motor's full-load current falls within the adjustable range. Always install in a suitable enclosure to achieve the IP65 front protection rating.
