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

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

The ONESTO KC6-K miniature circuit breaker is used for protecting electrical circuits against overload and short circuits. The thermal trip mechanism is responsible for overload protection, while the electromagnetic trip mechanism ensures rapid disconnection in the event of a short circuit.

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

Technical specifications:

• Series: KC6-K
• Number of poles: 1
• Rated current: 6 A
• Tripping characteristic: C
• Rated short-circuit breaking capacity: 6 kA
• Rated voltage according to the 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 high inrush currents. It can be used, among other applications, for selected devices with motors or transformers, provided that the necessary protective conditions are met.

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