Commel Miniature Circuit Breaker 20 A 1P B 6kA

Product overview

The Commel miniature circuit breaker 20 A 1P B 6 kA is designed for the reliable protection of household and similar electrical circuits. With its B tripping characteristic, it provides fast, instantaneous disconnection in the event of overloads or short circuits, helping to reduce the risk of damage to equipment and wiring.

This 1-pole breaker is particularly suitable for circuits with predominantly resistive (ohmic) loads, such as heating devices or standard lighting circuits, where a B-curve device is typically recommended.

Key features

• Rated current: 20 A
• Number of poles: 1P
• Tripping characteristic: B (fast, non-delayed tripping)
• Breaking capacity: 6 kA
• Suitable for resistive (ohmic) loads
• Can be combined with pin or fork type phase busbars
• 35 mm DIN rail mountable, for quick and standard installation
• Operating ambient temperature: -5°C to +40°C
• Window for circuit labeling, for clear identification in the distribution board
• Colored status indicator for quick visual check of the breaker position

Wiring and installation

• Connectable conductor cross-sections:
  • Up to 25 A: up to 16 mm² flexible or 25 mm² solid conductors
  • From 32 A to 63 A: up to 25 mm² flexible or 35 mm² solid conductors

The breaker is designed for mounting on standard 35 mm DIN rails, making it suitable for most domestic and small commercial distribution boards. Compatibility with both pin and fork type busbars helps simplify installation and ensure a neat, organized panel layout.

Application

Use this Commel 20 A 1-pole B-curve miniature circuit breaker for protecting individual circuits in residential or similar installations where fast disconnection and reliable performance are required, particularly for circuits with mainly resistive loads.
