Residual Current Circuit Breaker 1P B 2A Kanlux 23156

Kanlux Residual Current Circuit Breaker 1P B 2A is a single-pole protective device designed to detect and interrupt residual (leakage) currents in low-voltage installations. With a B tripping characteristic and a rated current of 2 A, this device is intended to improve electrical safety by responding to earth faults and reducing the risk of electric shock and fire in residential and light-commercial applications.

Advantages

The device provides fast detection of leakage currents and reliable disconnection of the protected circuit. Its single-pole design allows integration into existing single-phase distribution systems where only the phase conductor requires residual-current protection. The B characteristic ensures compatibility with circuits that may contain moderate inrush currents from certain types of equipment. Compact dimensions make it suitable for distribution boards with limited space.

Suitable for

• Residential single-phase electrical circuits needing residual current protection
• Light-commercial installations with low-rated branch circuits
• Protection of specific loads or sub-circuits where single-pole interruption is acceptable

When it may not be suitable

This single-pole residual current breaker does not interrupt the neutral conductor; in installations where full disconnection of all conductors is required for safety or code compliance, a 2P or 4P device should be used instead. It is also not designed to replace overcurrent protection devices — it offers residual-current detection rather than primary overcurrent tripping. For circuits with higher rated currents than 2 A, a device with an appropriate rated current must be selected.

Key specifications

• Poles: single-pole (1P)
• Tripping characteristic: B
• Rated current: 2 A
• Function: residual (earth leakage) current detection and disconnection
• Application: low-voltage single-phase circuits in residential and light-commercial environments

How to use

Install the residual current circuit breaker in the distribution board according to local electrical standards and wiring diagrams. Connect the phase conductor through the device terminal and ensure proper tightening of terminals. After installation, test the device using its built-in test function or an external residual current tester to confirm correct operation. Regular periodic testing and inspection are recommended to ensure continued protection.

What to consider before purchase

• Verify that single-pole protection is acceptable for your local regulations and the intended circuit.
• Confirm that a 2 A rated current meets the requirements of the protected load and upstream protection coordination.
• Ensure compatibility with the distribution board space and terminal type.
• Check whether a device that also interrupts neutral or offers different sensitivity is required for your application.

Usage recommendations

Use this Kanlux 1P B 2A residual current breaker as part of a coordinated protection scheme: pair it with appropriate upstream overcurrent protection, follow local installation regulations, and perform regular functional tests to maintain safety in single-phase circuits.
