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

ONESTO KC6-K Circuit Breaker, 3-pole, 20A, type B, 6 kA

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

With a 3-pole design, a rated current of 20A, and a type B characteristic, this device can be selected to meet the requirements of the protected circuit. The nominal short-circuit breaking capacity is 6 kA.

Technical specifications:

• Series: KC6-K
• Number of poles: 3
• Rated current: 20A
• Trip characteristic: B
• 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 specified by the manufacturer: IEC 60898-1

Type B characteristic:

The type B characteristic is designed for protecting circuits with low inrush currents. It can be used, among others, in lighting circuits and resistive loads, after checking the parameters of the installation and load.

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.
