Residual current circuit breaker - 6 kA EFI6-P4 A 16/0.03 002061660

Reliable protection in your electrical installation

This four-pole residual current circuit breaker EFI6-P4 A 16/0.03 is a key element ensuring safety in every electrical circuit. Using it minimizes the risk of electric shock, protecting both people and devices from the effects of short circuits and insulation damage. It is a reliable solution for both professional installers and end-users looking for comprehensive protection.

Functionality and technical parameters

The circuit breaker is designed to operate in TN-S, TN-C-S, TT and IT networks, where the neutral and earth conductors are separated. Its rated current is 16 A, and the rated residual current is 30 mA – ideal for additional protection against direct contact. The short-circuit strength of 6 kA guarantees stable operation even in the event of overloads. Mounting is on a DIN rail, and the compact dimensions (width 4 modules, depth 68 mm) make installation easy even in tight distribution boards. The circuit breaker is characterized by a high operating frequency – 50/60 Hz – and a degree of protection IP20.

Ease of use and installation

The EFI6-P4 A 16/0.03 residual current circuit breaker is equipped with several practical solutions to facilitate its use and installation:

• Test button: allows regular checking of the circuit breaker's functionality.
• Contact position indicator: allows easy identification of the circuit breaker status (ON/OFF).
• Secured terminals: minimize the risk of accidental contact with live parts.
• Possibility of sealing: provides additional protection against unauthorized disconnection.
• Compatibility with accessories: possibility of mounting auxiliary contacts and other elements extending functionality.
• Wire connection: Supports solid and stranded wires with a cross-section from 1 to 25 mm².
• Wide operating temperature range: From -25°C to +55°C ensures reliable operation in various environmental conditions.

This makes installation quick and intuitive, and operation – simple and safe. The NL version with the neutral pole on the left side facilitates cable organization in the distribution board. Additionally, each circuit breaker has a unique QR code with technical data and measurement test results, ensuring full transparency and quality control.
