Overcurrent circuit breaker K60N-B63-3 B 63A 3-pole A9K01363

Safety and reliability in your electrical installation

The K60N-B63-3 circuit breaker is a three-pole protection device designed to protect electrical circuits in residential and commercial buildings. The rated current of 63A combined with characteristic B makes it an ideal solution for protecting sockets, lighting and heating circuits. The breaking capacity of 6kA guarantees effective disconnection in the event of a dangerous overvoltage.

Design and installation – comfort for the installer

This circuit breaker is distinguished primarily by its ease of installation. Thanks to the possibility of connecting wires both from above and from below (comb busbar or directly), installation is quick and flexible. Serrated terminals ensure a secure connection of the wires, minimizing the risk of accidental loosening. Additionally, the snap-action contact ensures independence of the closing speed of the contacts from the speed of operating the lever – this feature is particularly appreciated during dynamic installation work. The ability to lock the circuit breaker lever with a padlock increases safety and prevents unauthorized switching.

Functionality and technical parameters – protection tailored to your needs

The K60N-B63-3 circuit breaker has been designed with durability and reliability in mind. The electrical endurance of 10,000 cycles, thanks to the use of a snap-action contact, guarantees long-term operation even with frequent switching. Compliance with EN/IEC 60898-1 confirms the high safety standard and quality of the product. Energy limitation class 3 and surge category 2 provide adequate protection against the effects of disturbances in the electrical network. The width of 3 modules allows for efficient use of space in the switchgear cabinet. The cross-section of connectable solid wires is 1-25 mm², and stranded wires 1-16 mm², which gives a great freedom in choosing the appropriate cables. The device operates in a temperature range from -25°C to 70°C, which makes it resistant to changing environmental conditions.
