Product Description
Moeller ZM-40-PKZ2 thermal trip module that is adjustable from 32 to 42 AMPS and is used for installation into the PKZ2 base module. This trip block comes standard with Class 10 tripping so that it trips in 10 seconds or less in an over current condition. For a lower AMP range than the ZM-40-PKZ2, the range of 24 to 32 AMPS is available in the ZM-32-PKZ2 as are side mounted auxiliary contact blocks and under voltage trips.

Never confuse imitation with innovation!
Moeller designed the first PKZ “motor protective controller” in 1932! Since then, the term “PKZ” has become synonymous worldwide with these types of devices, regardless of manufacturer. Eight decades of continuous innovation has resulted in today’s best technology, built from the ground up, only by Moeller.
The Swiss Army Knife® of motor control
The base PKZ2 controller combines single-break power contacts with Class 10 thermal overload protection and current limiting short circuit protection to manually control motor loads. The PKZ2 can also be equipped with a high capacity contactor for remote control of individual or group motor loads. Collectively, the PKZ2 family is UL and CSA listed for a wide range of uses including:
- Manual Starter applications
- Group Fusing applications
- Motor Disconnect means
- Type E, Self-protected, Combination Starter applications
- Multi-motor Starter Combination applications
- Tap Conductor protection
Excellent control & protection with one frame size!
PKZ2 devices have a 42 amp continuous current rating. They control and protect motors to 30HP at 480V or 25HP @ 600V with one frame size. Their excellent current-limiting design clears fault currents of 100 KAIC at 240VAC; 65KAIC at 480VAC; and 42KAIC at 600VAC (all values RMS Symmetrical). The total clearing time of the device at the highest fault condition is a maximum of 3.5ms at 480V and 4.0ms at 600VAC.
