Three-pole circuit breaker 63A, type B, 6kA (KC6-K)

ONESTO KC6-K Circuit Breaker, 3-pole, 63A, characteristic B, 6 kA

The ONESTO KC6-K circuit breaker is used 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 case of a short circuit.

This 3-pole design, with a rated current of 63A and characteristic B, allows for the 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
• Tripping 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 indicated by the manufacturer: IEC 60898-1

Characteristic B:

Characteristic B is intended for protecting circuits with low inrush currents. It can be used, among others, in lighting circuits and resistive loads, after reviewing the installation and load parameters.

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