Circuit breaker 3P C 32A AC Kanlux 23155

Circuit breaker 3P C 32A AC Kanlux 23155 is a three-pole miniature circuit breaker with a C tripping characteristic and rated current of 32 A for alternating current systems. It is designed to protect multi-phase electrical circuits against overloads and short circuits in residential, commercial and light industrial installations. The device is suitable for snap-on DIN-rail mounting and for use in coordinated protection systems together with residual-current devices and other protective equipment.

Advantages

The three-pole design ensures simultaneous disconnection of all phases to prevent phase-to-phase faults and maintain system safety. The C-characteristic provides moderate inrush tolerance while offering reliable short-circuit protection for circuits with motors and general-purpose loads. Compact dimensions allow efficient use of distribution board space and standard DIN-rail compatibility simplifies installation and replacement. The construction complies with common safety and performance expectations for miniature circuit breakers and is suitable for coordinated operation with upstream or downstream protective devices.

Suitable for

• Protection of three-phase branch circuits in residential electrical panels
• Overload and short-circuit protection for small commercial installations
• Feeding general-purpose loads with moderate motor starting currents
• Use in coordinated protection schemes with residual-current devices

Key specifications

• Poles: 3 (three-pole)
• Tripping characteristic: C
• Rated current: 32 A
• Type of current: AC (alternating current)
• Mounting: DIN-rail (standard snap-on)
• Function: overload and short-circuit protection for multi-phase circuits

How to use

Install the circuit breaker into a compatible DIN-rail distribution board according to local electrical codes and wiring practices. Ensure the supply and load conductors are correctly connected to the designated terminals and tightened to the manufacturer's recommended torque. Coordinate protective settings with upstream devices and any residual-current devices to ensure selectivity where required. Verify correct operation by switching the breaker on and off under no-load conditions before energising connected equipment. Any installation, inspection or service should be performed by a qualified electrician.

Usage recommendations

Use this three-pole C 32A miniature breaker for balanced three-phase circuits with moderate inrush currents. For circuits with high motor starting currents or special coordination requirements, consider verification of selectivity and appropriate device characteristic selection. Periodically inspect terminal tightness and the general condition of the distribution board to maintain reliable protection.
