Residual current circuit breaker EFI-P4 AC 25/0.1 002061621

### Protection and safety in electrical installations

Residual Current Device (RCD) EFI-P4 AC 25/0.1 is a key element of every modern electrical installation, providing effective protection against electric shock and protecting devices from damage caused by short circuits and overloads. Its versatility makes it indispensable in both residential and industrial buildings.

This four-pole RCD, with a rated current of 25A and a tripping current of 0.1A, is designed to operate in AC networks with a voltage of 415V and a frequency of 50/60Hz. The use of AC characteristics makes it particularly effective in detecting alternating leakage currents, minimizing the risk of electric shock. This RCD is used in TN-S, TN-C-S, TT and IT networks, where the neutral and earth conductors are separated or combined.

Construction and mounting

The EFI-P4 AC 25/0.1 RCD has been designed for easy mounting on a DIN rail, which significantly speeds up the installation process. Its compact dimensions (width 4 modules, mounting depth 68 mm) allow for efficient use of space in the distribution board. The connection terminals allow connection of multi-strand and solid core wires with a cross-section of 25 mm², ensuring a solid and safe connection. Additionally, the terminal protection against accidental contact increases safety during maintenance work.

Applications and benefits

• Personal protection: effectively protects against electric shock in case of direct or indirect contact with live parts.
• Device protection: protects electrical equipment from damage caused by short circuits and overloads.
• Compliance with standards: meets the requirements of DIN VDE 0100-482 and IEC 60364-4-482 standards regarding fire protection.
• High reliability: thanks to a fully automated production line and rigorous measurement tests, it ensures long-lasting and trouble-free operation.
• Easy status identification: the main contact position indicator makes it easy to check whether the switch is on or off. The "Test" button allows for regular checking of the device's functionality.
• Conditional short-circuit strength: Short-circuit strength up to 10 kA ensures stable operation even in difficult operating conditions.
• Safety of use: The ability to seal the lever in the "On" and "Off" positions prevents unauthorized changes to the switch settings.
