Overview

The ABB K655VSL2-MAC04 is a 15/25kV, 600-ampere, 2-way vault-stretcher kit designed for medium-voltage cable installations in vaults or underground systems. This kit includes a fully shielded, fully submersible molded rubber housing with 100% peroxide-cured EPDM insulation and conductive materials for long-term reliability. The AC04 connector sizing supports stranded, compressed, solid, or compact conductors ranging from 750 to 1250 kcmil, with an insulation diameter range of 1.37 to 1.63 inches (34.8 to 41.4 mm). The kit features two aluminum shear bolts for secure mechanical connections and strain relief in vault environments. Key ratings include a maximum phase-to-ground operating voltage of 16.2kV, phase-to-phase voltage of 28kV, 140kV BIL impulse withstand, 45kV AC one-minute withstand, and 84kV DC 15-minute withstand. The product meets ANSI/IEEE Standard 386 (latest revision) and delivers 600A continuous current with 25kA symmetrical momentary rating for 10 cycles. The deadbreak design allows safe connection and disconnection in de-energized states using standard hand tools. Applications include utility, industrial, and commercial medium-voltage cable management in confined or underground spaces. The kit’s components are optimized for durability and ease of assembly, reducing installation time while maintaining electrical integrity. Optional accessories enable visible external separation, bypass, isolation, dead-ending, grounding, testing, and the addition of taps, surge arrestors, or fault current indicators. The vault stretcher housing is compatible with components such as K651CP, K650BIP, K650RTP, K650RTW, K650S1, K650T1, K650JX, and K650ETP for expanded functionality.
