Understanding Breaking Capacity: 6kA vs 10kA

The VOB4-63 series offers two breaking capacity options to match your installation requirements:

6kA Breaking Capacity (6000A)

• Ιδανικό για: 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

• Ιδανικό για: 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
• Συστήματα HVAC
• 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
