Moeller PKZM1

The older style PKZM0-xx-NA was replaced by the PKZM1 series. The PKZM1 series was temporarily replaced with the MPS series. The older styles ( PKZMO-xx-NA, PKZM1-xx, MPS-xx ) are now retired and replaced with the upgraded PKZM0 series. The PKZM1 & MPS are identical in form, fit, function and rating’s, however the modern updated series PKZM0 is quite different and upgraded. When upgrading to the new PKZM0 series the following considerations apply |
| 1 | All are din rail mount. |
| 2 | The new PKZM0 series has a rotary operator knob instead of the older style stop and start button. |
| 3 | If the buss bar
connections were used for line connections, the old
buss bars will not fit the new series. If this is the
case all PKZ’s in the row must be upgraded to the new PKZM0 series and a new buss bar
used, or remotely mount the new PKZM0 and use wire for the power
feed. |
