Residual current circuit breaker EFI-P4 A 63/0.03 002061513

Safety first – Residual Current Device EFI-P4 A 63/0.03

This four-pole Residual Current Device (RCD) is a key element of any electrical installation, providing protection for people and equipment against the effects of electric shock and damage caused by short circuits and overloads. The EFI-P4 A 63/0.03 model, manufactured by ETI POLAM, is characterized by high reliability and precision, as confirmed by its popularity among professional installers and end-users.

This circuit breaker is designed to operate in AC networks with a voltage of 415V and a frequency of 50/60 Hz. Its rated current is 63A, and the rated differential current is only 0.03A – this value ensures a quick response in the event of a leakage current to ground, minimizing the risk of electric shock. Equipped with characteristic A, the circuit breaker effectively reacts to both AC and pulsating DC currents, which increases the scope of its applications.

#### Construction and mounting

The EFI-P4 A 63/0.03 circuit breaker is mounted on a standard DIN rail, which facilitates its installation in electrical distribution boards. Its width, 4 modules, allows for efficient use of space in the switchgear cabinet. The connection terminals allow the connection of multi-wire and solid-core wires with a cross-section of up to 25 mm², which provides flexibility in the selection of power supply cables. Additionally, the IP20 degree of protection prevents accidental contact with live parts.

#### Application and benefits

This residual current device is widely used in residential, commercial and industrial buildings. It is ideal for protecting lighting circuits, socket outlets and electrical appliances exposed to moisture or direct human contact. Its high short-circuit strength (10 kA) guarantees reliable operation even in the event of serious disturbances in the electrical network.
