Description
ABB GLB0201
- Technical Specifications (typical):
- Busbar Size Accepted: 5 × 30 mm to 10 × 80 mm (flat bar) — confirm exact per GLB series datasheet
- Rated Voltage: ≤1000 V AC (low-voltage insulation)
- Rated Short-Time Withstand Current (Icw): Matches busbar rating (typically 10–50 kA / 1 s)
- Creepage Distance: ≥12 mm (per IEC 60664for 1000 V)
- Material: DMC (Dough Molding Compound) or BMC — flame-retardant, halogen-free, UL 94 V-0
- Fixing: M6 or M8 screw to panel / frame; clamp screw for busbar
- Color: White, beige, or red-brown
- Operating Temp.: –40 °C to +120 °C (short-term)
- Functional Features:
- Phase-barrier design — separates A/B/C/N busbars at defined spacing (typically 30–50 mm center-to-center)
- Slotted clamp allows busbar thermal expansion without loosening
- Can be stacked or ganged for multi-tier bus arrangements
- Application Scenarios:
- Main distribution board (MDB) busbar fixing
- Motor Control Center vertical bus support
- S800 / S200 panel internal busbar spacing
- Retrofit busbar insulation in legacy LV cubicles
- Material & Structure / Working Principle / Installation / Precautions:
- Bolt to panel/chassis at marked positions; insert busbar into clamp slot; tighten clamp screw to spec (avoid over-torque which cracks DMC)
- Verify busbar phase spacing complies with clearance requirement for system voltage (IEC 61439-1/2)
- Do NOT use in medium-voltage (>1 kV) applications — not rated for higher BIL
- Periodically inspect for cracking in DMC material in high-humidity/high-pollution environments
