Single-pole circuit breaker 40A, characteristic C, 6kA (KC6-K)

ONESTO KC6-K Circuit Breaker, Single Pole, 40 A, Type C, 6 kA

The ONESTO KC6-K circuit breaker is used to protect electrical circuits against overloads and short circuits. The thermal trigger is responsible for overload protection, while the electromagnetic trigger provides quick disconnection in case of a short circuit.

With a single pole design, a rated current of 40 A, and a C characteristic, this device can be tailored to the requirements of the circuit being protected. The rated short-circuit breaking capacity is 6 kA.

Technical Data:

• Series: KC6-K
• Number of poles: 1
• Rated current: 40 A
• Tripping characteristic: C
• Rated short-circuit breaking capacity: 6 kA
• Rated voltage per catalog: 240/415 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

C characteristic:

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

The selection of the circuit breaker should be adjusted to the load, cross-section, and current-carrying capacity of the wires, as well as the short-circuit conditions of the installation.
