3-pole circuit breaker 20A, type C, 6 kA (KC6-K)

ONESTO KC6-K Circuit Breaker, 3-pole, 20 A, Type C, 6 kA

The ONESTO KC6-K circuit breaker is designed to protect electrical circuits from overload and short circuits. The thermal trip mechanism provides overload protection, while the electromagnetic trip mechanism ensures rapid disconnection in the event of a short circuit.

The 3-pole design, rated current of 20 A, and Type C characteristic allow the device to be suited for the requirements of the protected circuit. The rated short-circuit breaking capacity is 6 kA.

Technical specifications:

• Series: KC6-K
• Number of poles: 3
• Rated current: 20 A
• Trip 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 high 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 matched to the load, cross-section, and current-carrying capacity of the wires, as well as to the short-circuit conditions of the installation.
