3-pole circuit breaker 63A, type C, 6 kA (KC6-K)

ONESTO KC6-K Circuit Breaker, 3-pole, 63A, Type C, 6 kA

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

Its 3-pole design, rated current of 63 A, and Type C characteristic allow for appropriate selection of the device according to 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: 63A
• Trip characteristic: C
• Rated short-circuit breaking capacity: 6 kA
• Rated voltage per catalog: 415 V AC
• Rated frequency: 50/60 Hz
• Rated insulation voltage: 415 V
• Rated impulse voltage withstand: 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 having high inrush currents. It can be used, among other applications, 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 current-carrying capacity of the wires, as well as the short-circuit conditions of the installation.
