## Summary description

Single-pole miniature circuit breaker Kanlux KMB6-B4/1 rated B curve, 4 A nominal current and 6 kA breaking capacity for AC circuits. Designed for overcurrent protection in residential and light commercial distribution boards, it provides thermal-magnetic tripping for short-circuit and overload protection. Compact module for DIN-rail mounting, compliant with VDE reference 23179.

## Long description

Miniature circuit breaker 1P B 4A 6kA AC Kanlux KMB6-B4/1 is a single-pole protective device designed for installation in residential and light commercial distribution boards. The device uses a B-curve characteristic and a nominal current rating of 4 A to provide thermal-magnetic protection against overloads and short circuits in AC circuits. The compact housing is intended for DIN-rail mounting and meets applicable safety and performance expectations for modular circuit breakers.
Advantages
The breaker combines a B curve tripping characteristic with a 4 A nominal rating to ensure timely disconnection of low-inrush circuits and reliable protection of lighting and socket circuits. A rated breaking capacity of 6 kA supports safe interruption of fault currents typical for small distribution systems. The compact single-pole design saves space in the distribution board and enables straightforward integration with standard DIN-rail accessories and wiring practices.
Suitable for
 Protection of lighting circuits in homes and apartments
 Overcurrent protection for socket outlets and small appliances
 Use in small commercial electrical panels and service cupboards
 Applications requiring DIN-rail modular components and compact breakers
Key specifications
 Poles: single-pole (1P)
 Tripping characteristic: B-curve (suitable for resistive loads and limited inrush)
 Nominal current: 4 A
 Rated breaking capacity: 6 kA (AC)
 Mounting: standard DIN-rail modular housing
 Operation type: thermal-magnetic trip (overload and short-circuit protection)
 Application: alternating current (AC) circuits
How to use
Install the miniature circuit breaker on a standard 35 mm DIN-rail inside the distribution board following local wiring regulations and safety standards. Connect the phase conductor to the breaker input terminal and the load conductor to the output terminal, ensuring secure screw connections and proper conductor cross-section for a 4 A circuit. Verify polarity and tighten terminals to the manufacturer's recommended torque. After installation, test the circuit under no-load conditions and verify correct operation by switching the device on and off. For fault conditions, the thermal-magnetic mechanism will trip automatically; reset the breaker manually after the fault is cleared.
Usage recommendations
 Use this 1P B 4A breaker in circuits where low nominal current protection is required, such as lighting runs or dedicated small-appliance lines. Avoid applying it to motors or high-inrush devices that require C- or D-curve characteristics. Ensure coordination with upstream protection and compliance with local electrical codes; if in doubt, consult a qualified electrician for selection and installation.
