Circuit breaker Kanlux 1-pole B curve 20 A model 23142

The Kanlux 1-pole B curve 20 A model 23142 is a single-pole miniature circuit breaker designed for overcurrent protection in residential and light commercial electrical installations. Compact and intended for DIN-rail mounting, this device provides thermal-magnetic tripping with a B-type characteristic that responds quickly to short-circuit currents while allowing for small inrush currents typical of lighting and small motors. It is suitable for protecting lighting circuits and general-purpose branch circuits up to 20 amps.

Advantages

This miniature circuit breaker offers a balance of compact size and reliable protection. Its B curve characteristic ensures sensitivity to short-circuit conditions while tolerating normal motor and lamp inrush currents, reducing nuisance trips. Designed for standard distribution boards, the breaker features DIN-rail compatibility and a single-pole form factor to save space in panel assemblies. The unit is intended to provide stable thermal-magnetic performance for everyday circuit protection tasks.

Suitable for

• Protection of lighting circuits in homes and apartments
• Protection of small appliance and socket circuits in residential spaces
• Use in small commercial or office distribution boards
• Retrofit and new installations that require compact single-pole protection

Key specifications

• Poles: single-pole
• Tripping characteristic: B curve (thermal-magnetic)
• Rated current: 20 A
• Mounting type: DIN-rail compatible
• Application: overcurrent protection for lighting and general-purpose circuits

How to use

Install the breaker on a standard 35 mm DIN-rail inside the distribution board, observing local electrical codes and safety practices. Connect the phase conductor to the line terminal and the load conductor to the load terminal, ensuring secure tightened connections. Use the breaker as part of a coordinated protection scheme; coordinate with upstream and downstream devices as required. Test the circuit after installation by switching the breaker on and off to verify mechanical operation and by applying appropriate testing procedures to confirm electrical protection.

Usage recommendations

Use this 20 A B-curve breaker for lighting and general circuits where moderate inrush currents occur; avoid using it for circuits with high motor starting currents that require C or D curve characteristics. Follow local regulations for earthing, neutral connections, and overall distribution board layout. Periodically inspect terminal tightness and visual condition, and replace devices that show signs of damage or corrosion.
