Residual current circuit breaker 3P+N 125A 500mA 10kA A CGA690

Protection of electrical installations and people

Residual Current Device (RCD) 3P+N is a key safety element in every electrical installation. This device, with a rated current of 125A and a sensitivity of 500mA, effectively protects against electric shock and prevents fires caused by short circuits and overloads. Its 3P+N design makes it ideal for protecting three-phase circuits with a neutral wire.

Functionality and application

The Type A RCD reacts to leakage currents to earth, making it indispensable in places with an increased risk of electric shock, such as bathrooms, kitchens, and utility rooms. DIN rail mounting simplifies installation and integration with the existing protection system. A rated differential current of 0.5A ensures a quick response in the event of a failure, minimizing the risk of damage and hazards to users. Short-circuit strength of 10kA guarantees stable operation even in the event of high voltage surges.

Construction and technical parameters

The device is characterized by a solid construction and high quality of workmanship. A width of 4 modules allows for efficient use of space in the distribution board. The cross-section of the connectable single-wire conductor up to 50mm² and multi-wire conductor up to 35mm² ensures compatibility with different types of cables. A mechanical lock prevents accidental switching on of the switch after it has been switched off by the protection device, further increasing safety. Operation in a temperature range from -25°C to 40°C enables its use in various environmental conditions. The rated impulse withstand voltage Uimp is 4kV, confirming resistance to sudden voltage changes. The degree of protection IP20 provides protection against contact with fingers and against the ingress of solid objects larger than 12.5 mm.
