Residual current circuit breaker EFI-P4 A 16/0.5 002061540

Safety and protection in your electrical installation

Residual Current Device (RCD) EFI-P4 A 16/0.5 is a key element of every modern electrical installation, providing protection for people and devices against the effects of electric shock and damage caused by short circuits and overloads. This device, designed for DIN rail mounting, effectively reacts to leakage currents, minimizing the risk of electrical hazards. Its solid construction and high quality workmanship guarantee reliable operation for a long time.

Functionality and application

The RCD type A is sensitive to both AC differential currents and pulsating DC currents, making it a universal solution for a wide range of applications. It will work in TN-S, TN-C-S, TT and IT networks. The use of a 16A rated current and 0.5A differential current circuit breaker is particularly recommended in lighting circuits, general-purpose sockets and in rooms with increased humidity. This ensures comprehensive protection in your home, workshop or office.

Technical characteristics and benefits

This four-pole circuit breaker (IP20) is characterized by high impact current resistance (0.4 kA) and short-circuit strength at 10 kA. The possibility of connecting multi-wire and solid-core wires with a cross-section of 25 mm² provides flexibility during installation. The width of 4 modules facilitates mounting in a distribution box. It is worth noting the insulation rated voltage Ui of 440V and the rated voltage of 415V - these parameters guarantee safe operation of the device in standard network conditions. Additionally, the "Test" button allows for regular checking of the circuit breaker's functionality, and the contact position indicator makes it easy to identify the device's status (ON/OFF). The terminal block design allows the use of insulated busbars, which increases installation safety.
