FAQ

What is the function of the attached NHI-E-11-PKZ0 auxiliary contact?

The NHI-E-11-PKZ0 is an auxiliary contact block that provides additional signaling contacts. The "-11-" designation indicates it has one Normally Open (NO) and one Normally Closed (NC) contact, which can be used for status indication in a control cabinet, such as signaling a trip condition to a PLC.

How do I correctly set the overload protection current on the PKZM0-2,5?

The overload protection is set using the yellow dial on the front of the device. You should set the dial to match the motor's full-load ampere (FLA) rating as specified on the motor's nameplate. The adjustable range for this model is 1.6 to 2.5 Amperes.

Is this PKZM0-2,5 suitable for use in potentially explosive atmospheres?

Yes, this unit carries an ATEX certification mark (Ex II(2)GD) and PTB 02 ATEX 3151, which makes it suitable for use in specific hazardous environments. However, it is crucial to verify that the specific zone and gas/dust group requirements of your application match the device's certification before installation.
