Blog - Product Modification

March 1st, 2021

Marathon Special Products is announcing a change in the design of the molding for our Class H Fuse Panel Fuse Holders. This product change is due to new tooling needed to maintain the product line, as well as utilizing a sustainable/recyclable material for the insulator base. This will be a running change that has no effect on part numbers or agency certification. The only rating change is the relative temperature index (RTI) rating of the insulator material noted below. This new, lower rating is still equal to or better than many other components utilized in the same panels these are used in today, and 50°C higher than what most industrial control panels are approved to operate at (75°C).

Old Version New Version
Insulator Material General Purpose Phenolic Thermoplastic, Glass filled Polycarbonate
Insulator RTI Rating 150°C 125°C
Insulator Surface Finish Semi- Gloss Flat/matte
Recyclable/Sustainable Materials No Yes
Robustness Brittle, low impact strength Robust, high impact strength
Weight Baseline existing models 25% reduction (average)
Other Component Materials Same
Dimensions (LxWxD) Same
Catalog Numbers Same
UL File Numbers Same
