Residual current circuit breaker EFI-P4 AC 16/0.3 002061630

Highly reliable protection for installations and people.

The EFI-P4 AC 16/0.3 residual current circuit breaker (RCCB) is a key element of every safe electrical installation. It provides protection 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. This is an indispensable solution for both residential and industrial buildings.

Universal application and compliance with standards

This circuit breaker is used in TN-S, TN-C-S, TT and IT networks where the neutral and earth conductors are separated. In accordance with DIN VDE 0100-482 and IEC 60364-4-482 standards, residual current devices with a differential current of up to 300 mA are essential to ensure fire protection in TN and TT systems. In installations with a potential fire hazard, such as infrared ceiling heaters, it is recommended to use circuit breakers with a differential current of 30 mA.

Key features and benefits

• High efficiency: A rated differential current of 0.3 A ensures a quick response to dangerous leakage currents.
• Durability: Short-circuit strength of 10 kA guarantees reliable operation even in the event of overloads.
• Universal mounting: DIN rail mounting simplifies installation and integration with existing electrical infrastructure.
• Safety: IP20 protection degree protects against accidental contact with live conductors.
• Practical solutions: A 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).
• Compatibility with accessories: The ability to mount additional accessories (auxiliary contacts, release devices) expands the functionality of the circuit breaker.
• Solid construction: Made of high-quality materials ensures long-lasting and trouble-free operation.
• Wire cross-section: Supports stranded and solid core wires with a cross-section of 25 mm², providing flexibility when selecting wires for the installation.

Technical parameters for professionals
