Single-pole circuit breaker 63A characteristic C 6kA (KC6-K)

ONESTO KC6-K Circuit Breaker, single-pole, 63 A, type C, 6 kA

The ONESTO KC6-K circuit breaker is designed to protect electrical circuits from 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.

The single-pole design, nominal current of 63 A, and C characteristic make it suitable for the requirements of the protected circuit. The nominal short-circuit breaking capacity is 6 kA.

Technical specifications:

• Series: KC6-K
• Number of poles: 1
• Nominal current: 63 A
• Trip characteristic: C
• Nominal short-circuit breaking capacity: 6 kA
• Nominal voltage according to the catalog: 240/415 V AC
• Nominal frequency: 50/60 Hz
• Nominal insulation voltage: 415 V
• Nominal withstand voltage: 4 kV
• Standard specified by the manufacturer: IEC 60898-1

C characteristic:

The C characteristic allows for the protection of circuits with loads that have high 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 adjusted to the load, cross-section, and current-carrying capacity of the wires, as well as the short-circuit conditions of the installation.
