Circuit breaker iC60N-B63-4 B 63A 4-pole A9F03463

Overcurrent circuit breaker iC60N-B63-4 is a four-pole protection for electrical installations, designed to protect against the effects of overloads and short circuits. The device with a rated current of 63A is characterized by its versatility – it will work in residential, commercial and industrial buildings. The breaker design allows for direct connection of wires with a cross-section from 1 to 35 mm² (solid) or from 1 to 25 mm² (stranded), which facilitates installation and adaptation to various installations.

Protection and functionality

The iC60N-B63-4 circuit breaker has a B tripping characteristic, which means it reacts quickly to current increase, but is tolerant to short-term surges, typical of starting devices with motors. The rated short-circuit breaking capacity (Icn) is 6kA at 400V and 230V, and the Icu capacity according to IEC 60947-2 is 10kA and 20kA respectively. This ensures effective protection of the circuit against damage caused by overvoltage. The energy limitation class is 3, which affects the cost of protecting the downstream circuit. The rated insulation voltage Ui is 500V, and the rated impulse withstand voltage Uimp is 6kV.

Comfort of use and installation

The iC60 series is distinguished by a well-thought-out design that makes work easier for both installers and users. The VisiTrip indicator signals the operation of the breaker due to a disturbance (red color), allowing for quick identification of the problem. Additionally, the VisiSafe indicator informs about the physical opening of the contacts (green color), ensuring safety during maintenance work. The breaker can be easily removed from the DIN rail without tools, and the double terminals allow connection of wires from the top or bottom. Its width is 4 modules.

Additional information

iC60N circuit breakers are made of environmentally friendly materials – they are halogen-free and have REACh and RoHS declarations. Power losses are 5.6W at 400V. The degree of protection IP20 provides basic protection against accidental contact. The device operates in the range of ambient temperatures from -35°C to +70°C and at a frequency of 50 to 60 Hz. The possibility of additional equipment increases the functionality of the device and allows it to be adapted to specific installation needs.
