Three-pole circuit breaker 40A, type C, 6 kA (KC6-K)

ONESTO KC6-K Circuit Breaker, 3-pole, 40 A, Type C, 6 kA

The ONESTO KC6-K circuit breaker is designed to protect electrical circuits against overload and short circuit. The thermal release is responsible for overload protection, while the electromagnetic release ensures quick disconnection in the event of a short circuit.

The 3-pole design, rated current of 40A, and C characteristic allow for proper selection of the device to meet the requirements of the protected circuit. The rated short-circuit breaking capacity is 6 kA.

Technical Data:

• Series: KC6-K
• Number of poles: 3
• Rated current: 40A
• Release characteristic: C
• Rated short-circuit breaking capacity: 6 kA
• Rated voltage according to the catalog: 415 V AC
• Rated frequency: 50/60 Hz
• Rated insulation voltage: 415 V
• Rated impulse withstand voltage: 4 kV
• Standard indicated by the manufacturer: IEC 60898-1

Type C Characteristic:

The Type C characteristic allows for the protection of circuits with loads that have elevated inrush currents. It can be used for selected devices with motors or transformers, provided that the required protection conditions are met.

The selection of the circuit breaker should be adapted to the load, cross-section, and ampacity of the wires, as well as the short circuit conditions of the installation.
