Residual current circuit breaker EFI-P4 AC 16/0.1 002061620

Protection and safety in electrical installations

Residual Current Device (RCD) EFI-P4 AC 16/0.1 is a key element ensuring safety in every electrical installation. It serves 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. It is indispensable in TN-S, TN-C-S, TT and IT networks, where proper separation of neutral and earth conductors is crucial for safety.

This four-pole RCD with a rated current of 16A and an AC sensitivity of 0.1A, finds application in both residential and commercial buildings. Its versatility makes it ideal for securing lighting circuits, socket outlets and electrical devices exposed to moisture. Thanks to its construction and parameters, it provides effective fire protection in accordance with DIN VDE 0100-482 and IEC 60364-4-482 standards – particularly important in installations with a potential fire risk.

Construction and mounting

The EFI-P4 AC 16/0.1 RCD is characterized by a solid construction and easy mounting on a DIN rail. Its width of 4 modules allows for efficient use of space in the distribution board. The connection terminals are adapted for multi-wire and solid-core wires with a cross-section of 25 mm², which ensures a secure connection and minimizes the risk of loosening connections. The IP20 degree of protection guarantees protection against accidental contact. Additionally, the RCD has a testing function with a "Test" button, allowing for regular control of its efficiency, and a contact position indicator facilitating identification of the switch status (ON/OFF).

Technical parameters and compliance with standards

The EFI-P4 AC 16/0.1 residual current device has been designed with reliability and durability in mind. Its short-circuit strength is 10 kA, which ensures resistance to sudden current surges during short circuits. Operation in the rated voltage range of 415 V and frequency of 50/60 Hz guarantees compatibility with most electrical installations. Compliance with standards ensures a high level of safety and confirms the quality of the product. The impulse withstand voltage is 0.4 kA and the rated insulation voltage Ui is 440V.
