Residual current circuit breaker EFI-P2 AC 16/0.03 002061210

Residual Current Device (RCD) is a key element of any electrical installation, ensuring the safety of users and equipment. The EFI-P2 AC 16/0.03 model is a reliable device designed to protect against electric shock, both from direct and indirect contact with live parts. It also protects devices from damage caused by short circuits or leakage currents.

This two-pole switch, mounted on a DIN rail, is characterized by a rated current of 16 A and a differential current sensitivity of 0.03 A. This means it reacts to small leakage currents, providing quick and effective protection. Its construction based on AC technology makes it sensitive to alternating currents, which is standard in most domestic and industrial installations. The short-circuit strength of 10 kA guarantees its stable operation even in the event of large voltage surges.

The use of RCDs is regulated by IEC/EN 61008, DIN VDE 0100-482 and IEC 60364-4-482 standards. It is important to select the correct value of the differential current – for additional protection (direct contact) it is recommended to use switches with a value ≤ 30 mA, and for fire protection – ≤ 300 mA. This model with a current of 0.03A is ideal for applications requiring high sensitivity, e.g. in circuits powering electronic devices or in rooms with increased humidity.

• Safety first: protects against electric shock and prevents fires caused by insulation damage.
• Versatility: suitable for TN-S, TN-C-S, TT and IT networks.
• High reliability: thanks to the automated production line of ETI Polam and measurement tests, each switch has a unique QR code with technical and production data.
• Easy diagnostics: the "Test" button allows you to check the functionality of the switch, and the contact position indicator makes it easy to identify the device status (ON/OFF).
• Comfort of installation: the ability to seal the lever and use insulated busbars facilitates installation and ensures safety of use.
• Solid construction: impact current resistance is 0.4 kA, which ensures long-term and trouble-free operation of the device.
• Flexibility: possibility of mounting additional accessories (auxiliary contacts, release triggers).

The EFI-P2 AC 16/0.03 switch will find application in both domestic installations (protection of lighting circuits, sockets in bathrooms) and industrial installations (protection of machines and electrical equipment). Its compact dimensions (width of 2 modules) allow for easy placement in a distribution box. The cross-section of the connected multi-core and solid wire is from 1 to 25 mm², which ensures compatibility with various types of installation cables. The degree of protection IP20 protects against finger contact and the ingress of solid objects larger than 12.5 mm – important for ensuring safe operation in various environmental conditions.
