Understanding Breaking Capacity: 6kA vs 10kA
The VOB4-63 series offers two breaking capacity options to match your installation requirements:
6kA Breaking Capacity (6000A)
- Найкраще для: Residential buildings, small commercial offices, light industrial facilities
- Typical installations: 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
- Найкраще для: Industrial plants, large commercial buildings, high-power equipment installations
- Typical installations: Motor control centers, industrial automation, heavy machinery protection
- Fault current handling: Up to 10,000 amperes short-circuit protection
- Additional safety margin: 67% higher capacity than 6kA for demanding applications
How to Choose: Calculate your installation’s prospective short-circuit current (PSC). For most industrial applications with transformers above 200kVA, 10kA breaking capacity is recommended.

Type C Curve MCB (5-10 × In) – Most Common
Best for general-purpose commercial and industrial applications:
- Motor-driven equipment (pumps, fans, compressors)
- Fluorescent and LED lighting with electronic ballasts
- Transformers and inductive loads
- Системи опалення, вентиляції та кондиціонування
- General power distribution panels
Type D Curve MCB (10-20 × In)
Best for high inrush current loads:
- Large industrial motors and motor starters
- Welding equipment and X-ray machines
- Large transformers with high magnetizing inrush
- Capacitive loads
- Industrial machinery with high starting currents
