Understanding Breaking Capacity: 6kA vs 10kA
The VOB4-63 series offers two breaking capacity options to match your installation requirements:
6kA Breaking Capacity (6000A)
- Terbaik untuk: Residential buildings, small commercial offices, light industrial facilities
- Instalasi umum: Lighting circuits, small motor loads, general power distribution
- Fault current handling: Up to 6,000 amperes short-circuit protection
10kA Breaking Capacity (10000A) – Recommended for Industrial
- Terbaik untuk: Industrial plants, large commercial buildings, high-power equipment installations
- Instalasi umum: Motor control centers, industrial automation, heavy machinery protection
- Fault current handling: Up to 10,000 amperes short-circuit protection
