Overcurrent circuit breaker K60N-B40-3 B 40A 3-pole A9K01340

Reliable protection for electrical installations – Schneider Electric K60N-B40-3 circuit breaker

This three-pole circuit breaker from Schneider Electric's K60N series is a solid and proven solution for protecting electrical circuits in residential and commercial buildings. Designed for effective protection against overloads and short circuits, it ensures the safety of installations and electrical devices. Characteristic B means that the circuit breaker reacts quickly to current increases, but is also tolerant of short-term surges, which is particularly important when connecting devices with motors.

Functionality and installation for professionals

The K60N-B40-3 circuit breaker is distinguished by its versatility and ease of installation. Compatible with any commercially available DIN rail, which greatly simplifies and speeds up the work of installers. Double terminals (rail + wire) and knurled terminal surfaces guarantee secure and stable connections of wires with a cross-section from 0.5 to 35 mm² (solid) or 0.5 to 25 mm² (stranded). The trip indicator ensures independence of the closing speed of the contacts from the speed of operating the lever – this is an additional convenience during work.

Safety and technical parameters

The circuit breaker meets safety standards and has a rated short-circuit breaking capacity Icn of 6 kA at both 230 V and 400 V. The rated insulation voltage Ui is 440 V, and the rated voltage is 400 V. The IP20 degree of protection provides basic protection against accidental contact. The device operates in a temperature range from -25°C to 70°C and a frequency of 50-60 Hz. The energy limitation class is 3, and the surge category is 2. The width of the circuit breaker is 3 modules, which allows for optimal use of space in the switchgear.
