PRODUCT CHANGE ANNOUNCEMENT – 141 Series Power Blocks

Marathon Special Products is announcing a change in the design for 141 series power blocks.
Since the tooling for this product line needed replaced, we also incorporated as many
improvements as possible while limiting the impact on customers.

Functional Improvements are:

- Oblong Mounting Holes (center-to-center dimensions remain the same, but the oblong hole
allows flexibility in mounting)

- Snap-on Cover (vs. Screw-on)

- DIN Clearance (can drop over DIN rail and mount to panel without cutting out rail section)

- Improved Aesthetics

- Removes Pole Step (to make symmetrical)

General Changes are:

- Minor Dimensional Changes (width and height only – see drawings below)

- Dovetail Removal

This is a running change with no changes t o the par t nu mber s or rat i ng s .
Products will be converted to the new insulator base on December 5, 2016, so all orders taken

after that will be on the new insulator base. F eel free to e-mail or call with any questions about
this change.

Kind regards,
