Circuit breaker Kanlux 1P B 25A model 23147 – single-pole overcurrent protection, B characteristic, 25 A

The Kanlux single-pole circuit breaker model 23147 provides overcurrent protection for a single phase with a B tripping characteristic and a rated current of 25 A. Designed for mounting on standard DIN rails, this miniature circuit breaker is intended for residential and light commercial electrical installations where selective, reliable disconnection of a single phase is required. The device interrupts overloads and short-circuit currents within its characteristic curve to protect wiring and connected equipment.

Advantages

The B characteristic ensures tripping at lower fault currents compared with C or D curves, making this breaker suitable for protecting purely resistive or low-inrush loads while minimizing nuisance tripping. Compact single-pole design saves space in distribution boards and enables straightforward integration into existing panels. The device meets the functional requirements for overcurrent protection in typical home and small-business circuits and supports DIN-rail mounting for rapid installation.

Suitable for

• Protection of lighting circuits in homes and apartments
• Protection of socket outlets and small appliance circuits
• Use in small commercial or office electrical panels
• Replacement or upgrade of single-phase circuit protection in distribution boards

Key specifications

• Poles: single-pole (1P)
• Rated current: 25 A
• Tripping characteristic: B (magnetic trip at lower multiples of In)
• Mounting: standard DIN-rail
• Function: thermal-magnetic overcurrent protection (overload and short-circuit)

How to use

Install the circuit breaker on a compatible DIN rail inside a distribution board, ensuring correct orientation and secure connection of line and load conductors to the marked terminals. Switch off the main power before installation and confirm conductor cross-sections and tightening torques are appropriate for 25 A operation. After mounting and wiring, restore supply and verify correct operation by switching the breaker on and off and testing the protected circuit under controlled conditions.

Usage recommendations

Use this breaker where a B-type thermal-magnetic characteristic is required—typically for lighting and resistive loads with low inrush currents. Coordinate downstream protection and consider selective upstream devices to ensure proper discrimination. Follow local wiring regulations and, when in doubt, consult a qualified electrician for correct selection and installation.
