Overview

The Littelfuse 600V in-line watertight fuse holders (SKU: LEBAJ) are engineered for superior circuit protection in high-humidity and corrosive industrial environments. These robust fuse holders provide reliable performance where standard protection fails, ensuring the longevity and safety of electrical systems. Available in versatile configurations, including breakaway and non-breakaway options, as well as single and double pole designs, the LEBAJ series offers maximum flexibility to meet diverse application requirements. Specifically designed for harsh conditions, these fuse holders are ideal for outdoor installations, marine applications, and any industrial setting exposed to moisture and corrosive elements. Their watertight construction prevents ingress of water and contaminants, safeguarding the fuse and connection integrity. While the LEBAJ series is specified for 600V, Littelfuse also offers other inline fuse holder solutions for different voltage and current needs. For instance, the MINI Inline Fuseholder (SKU 0FHM0002SXJ and 0FHM0001SXJ) provides waterproof protection for MINI® fuses up to 30A at 32V, featuring 4-inch wire leads (14 AWG black or 12 AWG orange) and a protective cover for harsh environments. For applications requiring 3AG/3AB or SFE fuses, Littelfuse provides heavy-duty bayonet knob in-line fuseholders like the 150079, 155006A (6A), and 155004A (4A). These holders are designed for secure and quick fuse installation in demanding power distribution, industrial machinery, and automation systems. Littelfuse fuse holders are manufactured in the USA, ensuring high-quality construction and dependable performance. Whether you require high voltage protection in corrosive atmospheres or robust fuse solutions for general industrial use, Littelfuse offers a comprehensive range of products to meet your electrical safety and protection needs. Consult the product specifications for detailed current and voltage ratings applicable to each specific model.

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
