Residual current circuit breaker 3P+N 63A 100mA 6kA AC CEC463J

Safety and Reliability in Your Installation

This 3P+N residual current circuit breaker (RCCB) is a key element ensuring the protection of people and equipment in electrical installations. Designed to protect circuits with a rated current of 63A, it effectively detects leakage currents to earth, minimizing the risk of electric shock and preventing fires. Its construction, based on AC technology, guarantees reliable operation under typical usage conditions.

Functionality and Installation

The circuit breaker, mounted on a DIN rail, occupies a width of 4 modules, making it easy to integrate with existing distribution boards. Adapted to work with a voltage of 400V and a frequency of 50Hz, it meets the requirements of most standard electrical installations. The cross-section of solid wires from 1 to 25 mm² and stranded wires from 1 to 16 mm² ensures compatibility with various types of cabling. High surge current resistance (0.25 kA) and short-circuit strength at 6kA level testify to its solidity and durability.

Characteristics and Application

The rated differential current of 0.1A (100mA) provides effective protection against the effects of electric shock from indirect contact. This circuit breaker does not have a lock, which facilitates servicing and maintenance. A wide range of operating temperatures (-25°C to +40°C) allows it to be used in various environmental conditions. The possibility of expanding with additional equipment increases its functionality and adapts it to the individual needs of the installation. It should be remembered that this circuit breaker is intended for additional protection – it will not operate in the event of a short circuit between phases or to neutral, but it will effectively protect against touching a live enclosure. Its AC type sensitivity means it reacts to leakage currents with a sinusoidal waveform, which is typical of most household and industrial appliances.
