Overview

The Littelfuse 600V in-line watertight fuse holders (SKU: LECBAS) deliver reliable circuit protection in high-humidity and corrosive industrial environments. Designed for 10x38mm midget or Class CC fuses, these holders feature a high-heat, impact-resistant insulator and three O-rings per pole for a watertight seal. Blue O-rings indicate single-pole models, while red O-rings denote dual-pole versions for quick identification. Captive nuts and screws simplify installation, and polarized dual-pole versions ensure simultaneous disconnection. Optional breakaway models comply with highway commission standards for quick line-side disconnection during pole knockdowns, with fuses remaining safely encapsulated on the load side. Permanently installed neutral versions are marked with white nuts for easy identification. Rated for 600V AC/DC with a maximum current of 30A, these holders offer a Short-Circuit Current Rating (SCCR) of 200kA for Class CC fuses and 100kA for midget fuses. Operating temperature range is -40°C to 155°C. Applications include street lighting, parking lot lighting, traffic signaling, sports lighting, marine environments, and other humid or corrosive settings. Approved by UL (Class CC and midget) and CSA, these holders feature a tulip fuse clip design for optimal contact and low electrical losses. Lead-free solder ensures environmental compliance, and wire gauge markings on insulation boots simplify installation. Available in single and double pole configurations with optional insulation boots for enhanced sealing.
