Overview

The Littelfuse LECAAS series 600V in-line watertight fuse holders provide essential circuit protection in high humidity and corrosive industrial, marine, and outdoor environments. Engineered for reliability, these fuse holders are available in both breakaway and non-breakaway, single and double pole configurations, offering maximum application flexibility. The LECAAS series is designed to accept Littelfuse MINI® fuses, supporting a current range from 2A to 30A at a voltage rating of 32V. For robust connections, they come equipped with wire leads in either 14-gauge (regular duty) or 12-gauge (heavy duty) options. Superior watertight integrity is achieved through the use of three O-rings per pole, which are color-coded for rapid identification and streamlined installation and maintenance. The insulators are constructed from materials offering high resistance to both heat and impact, ensuring long-term durability in harsh conditions. Installation is further simplified and secured by captive nuts or screws, allowing for quick and dependable mounting. These fuse holders are meticulously engineered to withstand the rigors of challenging operational environments, delivering dependable performance and extended service life. The LECAAS series is a critical component for maintaining circuit integrity where standard fuse holders would fail due to environmental exposure.

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

Are Littelfuse Pre-Engineered panels compliant with industry standards?

Yes, these UL Listed, pre-built, customizable products are specifically designed to meet NEC® coordination requirements.

What are the benefits of high-resistance grounding?

High-resistance grounding limits point-of-fault damage and eliminates arc-flash hazards and transit overvoltages associated with ground faults.

How do Littelfuse arc-flash protection relays work?

Arc-flash relays detect a developing arc-flash incident and send a trip signal to interrupt power before significant damage occurs.

What do ground-fault protection relays detect?

Sensitive ground-fault relays with advanced filtering detect insulation resistance breakdown caused by moisture, vibration, chemicals, or dust.

What do trailing-cable protection relays monitor?

Trailing-cable protection relays continuously monitor the integrity of the ground conductor in portable cables. This protects cable-fed equipment from hazardous voltages caused by ground faults.
