JUNW K219/K220/K221 100A Fuse Cutout Sleeve

JUNW New-Generation Fuse Cutout Sleeves (Fuse Bases)
1.Core Product Value & Compliance
JUNW’s latest fuse cutout sleeves are engineered for low-voltage energy service protection, fully complying with the ErDF 69 40 070 French specification. The core competitive advantage is no need for additional wiring terminals, enabling direct, tool-friendly installation with a simple spanner. This eliminates extra component costs, cuts on-site labor time, and streamlines distribution network deployment. All models support zero-mechanical-load operation, allowing safe opening/closing under a maximum 63A load for reliable circuit protection.
1.Model K219: 100A Stripping Type
The K219 is a 100A stripping-type fuse cutout sleeve, matching 22x58 fuses for 100A-rated circuits. It supports 16–35mm² Al/Cu or 16M–50M Al conductors, requiring only simple cable stripping for direct installation (no additional terminals). Its spring-calibrated cartridge ensures fuses remain voltage-free on the customer side when opened, with mechanical tightening terminals for stable connections, a sealing cap for temporary protection, and sealable components for network security.
2.Model K221: 100A Insulation Piercing Type
The K221 is a 100A insulation piercing fuse base, compatible with 22x58 cylindrical fuses. It supports 6–35mm² Al/Cu conductors or 16M–50M Al conductors, with no cable stripping required—insulation piercing technology creates secure, low-resistance connections directly, no extra terminals needed. It boasts >6kV dielectric strength, shear-head tightening screws, and a sealable closing ring, making it ideal for overhead line distribution with robust weather and tamper resistance.
3.Model K220: 50A Compact Stripping Type
The K220 is a compact 50A stripping-type fuse base, designed for 14x51 fuses and 2.5–16mm² Al/Cu conductors. It enables direct installation without extra terminals, featuring a non-dismantlable shear-head screw for permanent, tamper-proof connections. Tailored for light-load overhead lines and small-scale metering, it offers reliable circuit protection, a compact footprint, and easy on-site deployment, perfect for residential and small commercial distribution networks.
