Residual current circuit breaker - 6 kA EFI6-P2 A 40/0.03 002061262

Safety and protection in your electrical installation

Residual Current Circuit Breaker (RCCB) EFI6-P2 A 40/0.03 is a key element ensuring the safety of using the electrical installation. Its task is to protect against electric shock, both in the case of direct and indirect contact with live conductors. Additionally, it protects electrical devices from damage caused by short circuits or leakage currents. Mounted on a DIN rail, this two-pole switch is indispensable in every modern circuit.

Functionality and application

The type A RCCB is sensitive to alternating currents and pulsating DC currents, making it a universal solution for most domestic and industrial applications. The rated current of 40A and the tripping current of 30mA provide effective protection for both people and equipment. Application in TN-S, TN-C-S, TT and IT networks guarantees compatibility with various types of electrical installations. It is worth remembering that in the case of protection against indirect contact, it is recommended to use circuit breakers with a differential current not greater than 300mA, and for additional protection – not greater than 30mA.

Technical characteristics and construction

The circuit breaker is characterized by a high short-circuit strength of 6kA, which ensures its reliable operation even in the event of overloads. Compact dimensions – width of 2 modules and depth of 68mm – make it easy to install even in crowded distribution boards. The cross-section of the connected conductor up to 25mm² allows you to connect conductors of different thicknesses, adapting to the specifics of the installation. A wide operating temperature range from -25°C to 55°C means that the circuit breaker can be used in various environmental conditions. Additionally, the presence of a contact position indicator makes it easy to identify the status of the switch (ON/OFF), and the ability to seal the lever prevents accidental changes in settings. The terminal design allows the use of insulated busbars on both the upper and lower terminals.
