Overview

The Littelfuse LECAAS series 600V AC/DC in-line watertight fuse holders deliver reliable circuit protection in high-humidity and corrosive environments. Designed for street lighting, marine systems, outdoor equipment, sports lighting, traffic signals, electric wheelchairs, and general outdoor circuit protection, these fuse holders ensure touch-safe operation and individual device disconnection to reduce shock risk during servicing. Key specifications include a 600V AC/DC voltage rating and support for MINI® fuses from 2A to 30A. The series offers both breakaway and non-breakaway configurations, as well as single and double pole versions, providing maximum application flexibility. Each pole features three O-rings for IP67 watertight integrity, with color-coded options for quick identification. The LECAAS series incorporates heat- and impact-resistant insulators, captive nuts and screws for simplified installation, and wire leads available in 14-gauge for regular duty or 12-gauge for heavy-duty use. The redesigned series includes an improved ergonomic grip for easier handling, pronounced seating for automatic alignment during installation, and chamfered edges to facilitate wire insertion.

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

Used as in-line protection for fluorescent fixtures, the Littelfuse LGR and LMF series fuses and LHR holder offer increased safety and reliability to lighting systems. On a 277 volt system, a fault occurring in an un-fused fixture could take out the entire branch circuit affecting up to 100 fixtures. This could cause safety problems as well as shut down operations. By individually fusing fixtures, these problems will be avoided. The added benefits of this is the ability to quickly identify the problem fixture and reduce the repair time. Fuse holders are rated up to 10 amperes at 300 volts and are equipped with 7” 18 AWG leads. Order part number LHR 000 for two leads, and part number LHR 001 for one lead and one terminal for insertion of 18 AWG ballast lead.
