Cole Hersee

<h3>About Cole Hersee</h3><p><strong>Cole Hersee</strong> has been a cornerstone of heavy-duty electrical engineering for over a century. The company traces its roots to 1914, when the Henry Cole Company was established in Boston, Massachusetts. In 1924, Leo Mayer acquired that firm, and by 1935 he had also purchased the F.C. Hersee Company — a specialist in automotive electrical components. The two were formally merged into the Cole Hersee Company in 1941, creating a brand whose name has since become synonymous with durable, purpose-built electrical components. In 2010, Cole Hersee was acquired by Littelfuse, Inc., expanding its reach and resources while preserving its long-standing commitment to quality.</p><p>Cole Hersee is recognized as a pioneer and leader in developing heavy-duty electrical products for the vehicle industry. The company collaborated on many foundational industry standards and today supplies over 2,000 dependable products and accessories for construction, agriculture, military, commercial trucking, and marine applications. It holds ISO 9001 certification, a testament to its rigorous manufacturing and quality management standards.</p><p>What sets Cole Hersee apart is its focus on purpose-built engineering for the harshest environments. Whether a component is destined for an offshore vessel, a long-haul semi-truck, or heavy construction equipment, Cole Hersee designs its products to withstand extreme conditions — resisting moisture, corrosion, UV exposure, and mechanical vibration. For decades, leading OEMs have chosen Cole Hersee as a preferred supplier, making their parts a familiar sight in factory-installed electrical systems across the globe.</p><h3>Core Product Categories</h3><p>Cole Hersee&apos;s catalog spans a wide range of critical electrical components.
