Feixe de cabos Pollmann Access KB Y87A 10mm² 4 polos L1/L2/L3=375mm N=425mm

Electricians and panel builders working on three-phase distribution boards often need a pre-assembled, reliable connection between the main supply and individual components. The Pollmann Access Cable Harness KB Y87A provides exactly that: a 4-conductor set with 10 mm² cross-sections, ready for installation in switchgear and control cabinets. Each phase conductor (L1, L2, L3) is cut to 375 mm, while the neutral (N) is 425 mm long to accommodate typical terminal block layouts, reducing the need for on-site cutting and stripping.

Key specifications

• Type: Cable harness / pre-assembled cable set
• Number of conductors: 4 (3-phase + neutral)
• Conductor cross-section: 10 mm²
• Conductor lengths: L1, L2, L3 = 375 mm; N = 425 mm
• Conductor material: Fine-stranded copper (Class 5 flexibility)
• Insulation: PVC
• Rated voltage: 600/1000 V
• Typical current rating: up to 63 A (depending on installation conditions)
• Color coding: Brown (L1), Black (L2), Grey (L3), Blue (N)
• End termination: Bare wire ends for screw or crimp connection
• Operating temperature range: -5°C to +70°C (fixed installation)

Why choose it

This harness saves time and ensures consistent quality. The conductors are pre-cut to the correct lengths, stripped, and ready for termination. The use of fine-stranded copper provides excellent flexibility for routing inside enclosures, while the PVC insulation offers good resistance to abrasion and common chemicals. The 10 mm² cross-section supports high current loads, making it suitable for main power distribution.

Ideal use cases

• Internal wiring of three-phase distribution boards
• Connection of main switches, circuit breakers, and terminal blocks
• Pre-wiring of control cabinets in industrial automation
• Retrofit and maintenance tasks where consistent cable lengths are required

Good to know

The harness is supplied as a set of four individual conductors, not a multi-core cable. The lengths are optimized for typical 18 mm pitch terminal blocks, allowing a clean and orderly installation. The bare ends are suitable for screw terminals, spring clamps, or crimp ferrules (not included).
