Overview

The Littelfuse LECDB (SKU: LECDB) is a robust 600V in-line watertight fuse holder designed for critical circuit protection in demanding industrial, marine, and outdoor applications. Engineered to withstand high humidity and corrosive conditions, this UL-listed and CSA-certified solution offers exceptional reliability. It accommodates both 10x38mm midget and Class CC fuses, providing flexibility for diverse protection needs. Available in single and double pole configurations, with breakaway and non-breakaway options, the LECDB ensures adaptability for any installation. Each pole features three internal O-rings for superior water resistance, with distinct blue (single pole) and red (dual pole) colored O-rings for easy identification and maintenance. Breakaway versions include cone-shaped insulator boots as standard for an additional watertight seal on conductors; non-breakaway units require optional boots. With a maximum current rating of 30A and a voltage rating of 600V AC/DC, the LECDB is ideal for street lighting, parking lot lighting, traffic signaling, sports lighting, boats, marinas, and other environments prone to moisture and corrosion. Its high heat and impact-resistant insulator, captive mounting hardware, and polarized dual-pole design enhance installation efficiency and operational safety. Certified to UL Listed Class CC Guide IZLT, UL Recognized Component Midget Guide IZLT2, and CSA Certified Class CC and Midget Class 6225, the LECDB meets stringent safety standards. The maximum interrupting rating is 200kA for Class CC fuses and 100kA for midget fuses. Its operating temperature range is -40°C to +125°C.

Mersen's complete line of single and dual pole in-line fuseholders accommodate Class CC fuses. The fuseholders are designed for quick installation. Securing nuts or screws are captive thus speeding installation by reducing the need to locate and assemble loose components in the field. Three internal O-rings per pole seal the fuseholder providing a water-resistant compartment for the fuse. The captive O-rings are colored (blue for single pole and red for dual pole) for quick detection. Optional cone shaped insulator boots can be slipped on to provide a watertight seal (breakaway versions come with boots standard). Both single and dual pole versions have an optional breakaway feature which safely disconnects the load in case of a pole knockdown. Fuses remain safely encapsulated within the watertight fuse holder on the load side. Once the pole has been reinstalled the fuseholder can be easily reconnected. single terminal boot
