Littelfuse Publishes Select Products in 3D on the TraceParts CAD Content Platform

CHICAGO, November 28, 2019 – Littelfuse, Inc., a global manufacturer of leading technologies in circuit protection, power control and sensing, has chosen TraceParts to promote a select group of its CAD models to millions of engineer-designers all over the world. The product groups selected include semiconductor fuses, solar fuses, fuse blocks and holders, protection relays and surge protection devices to protect against overcurrent, arc flash, ground fault, and power surges in industrial focused markets.

The Littelfuse Industrial Business Unit delivers vital products to address customer needs for protection, safe control and distribution of electrical power in industrial applications. Its portfolio includes a comprehensive line of products to minimize electrical safety hazards, limit equipment damage, improve productivity and safeguard personnel from injury due to electrical faults.

Littelfuse sought out a platform that specializes in CAD content where it could showcase products and reach its target audience: design engineers, panel builders, and people working in MRO (Maintenance Repair and Operations) roles.

“Our customers span several markets including renewable energy, onboard and off-board charging for electric vehicles, heating, ventilation, and air conditioning (HVAC), refrigeration, power conversion, mining, oil and gas, commercial construction and system integrators,” said Debra Jayson commercial marketing manager at Littelfuse. “Using TraceParts will enable us to target an even wider audience of design engineers.”

Littelfuse has been publishing its 3D and 2D CAD files at for several years. It decided to publish its CAD files and products on TraceParts due to their large following and exceptional user experience that allows engineers to view or download the 3D files easily from the platform.
