Residual current circuit breaker - 6 kA EFI6-P4 A 40/0.03 002061662

Safety and protection in your electrical installation

Residual Current Device (RCD) EFI6-P4 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 four-pole switch with a rated current of 40A and sensitivity A provides reliable protection in TN-S, TN-C-S, TT and IT networks.

Functionality and technical parameters

The EFI6-P4 A 40/0.03 RCD is characterized by high efficiency and a solid construction. The rated differential current at 30 mA provides additional protection, minimizing the risk of shock upon direct contact. Short-circuit strength of 6 kA guarantees stable operation even in the event of overloads. The device is designed to operate at temperatures from -25°C to 55°C, making it a universal solution for various environmental conditions. The cross-section of the connected solid or stranded wire up to 25 mm² ensures compatibility with most standard installations.

User comfort and installation

The switch has an indicator of the main contact position, making it easier to identify the device status (ON/OFF). The test button allows for regular checking of the correct operation of the switch, which is crucial for ensuring continuous safety. The terminals are protected against accidental contact under voltage, and the ability to seal the lever in the "On" and "Off" positions increases safety and prevents unauthorized changes to the settings. The compact width of 4 modules makes it easy to install in switchboards with limited space. Additionally, the terminal design allows the use of insulated busbars on both the upper and lower terminals, which greatly facilitates installation work.
