Overcurrent circuit breaker K60N-C40-3 C 40A 3-pole A9K02340

Overcurrent switch – reliable protection for electrical installations

This three-pole overcurrent switch K60N-C40-3 is a key element ensuring safety in electrical circuits. Designed to protect against the effects of overloads and short circuits, it performs well in both residential and commercial buildings. Characteristic C makes it ideal for circuits with devices generating surge currents, such as motors or transformers – it allows it to react more slowly to short current spikes, while effectively protecting against long-term overloads.

Design and parameters for professionals

The K60N-C40-3 switch is characterized by a compact design, taking up 3 modules in width. Its solid construction guarantees long-term and trouble-free operation. The rated current of 40A and high short-circuit breaking capacity (6kA at 230V and 400V) ensure effective protection of the electrical installation in the event of a failure. Thanks to the rated voltage of 400V, it is compatible with most standard installations. Made of high-quality materials, resistant to external factors, it meets safety standards and ensures reliable operation.

Comfort of assembly and use

The switch has double terminals at the bottom, allowing connection to both busbars and wires. Serrated terminals increase connection reliability and facilitate assembly. The snap-action contact ensures quick closing of the contacts regardless of the speed of the lever operation – this is particularly important in situations requiring a quick restoration of power. A wide range of wire cross-sections (0.5 - 35 mm² for solid and 0.5 - 25 mm² for stranded) provides flexibility during installation. Operation in a wide range of ambient temperatures (-25°C to +70°C) allows the switch to be used in various environmental conditions.
