Residual current circuit breaker EFI6-P2 AC 40/0.03 002061252

Safety and reliable protection with residual current circuit breaker EFI6-P2 AC 40/0.03

A residual current circuit breaker is a key element of any electrical installation, providing protection against electric shock and protecting devices from damage caused by leakage current. The EFI6-P2 AC 40/0.03 model from ETI Polam is a two-pole (2P) device designed for circuits with a rated current of 40A, with a residual current sensitivity of 30mA type AC. Using this circuit breaker minimizes the risk of electrical hazards in the home, workshop or other facility.

Functionality and application

The residual current circuit breaker protects against the effects of direct and indirect contact with live parts, and also prevents fires resulting from insulation damage. It is compatible with TN-S, TN-C-S, TT and IT networks, where the neutral and earth conductors are separated. Thanks to the 30mA sensitivity, it provides effective additional protection - i.e. protection of people against electric shock upon direct contact. The rated residual current value of 30A is a standard for protecting people in domestic and industrial installations.

Technical characteristics and construction

The EFI6-P2 AC 40/0.03 circuit breaker is characterized by high quality workmanship and durability. Mounting is done on a DIN rail, which facilitates integration with the existing distribution board. Its width of 2 modules allows for efficient use of space in the distribution cabinet. The device is adapted to work at temperatures from -25°C to 55°C and has a protection degree of IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm. Short-circuit strength at the level of 6kA guarantees safety in the event of a short circuit in the installation. Suitable for conductors with a cross-section from 1mm² to 25mm², both solid and stranded. The rated voltage is 240V, and the rated impulse withstand voltage is as high as 6kV – which proves high resistance to overvoltage.
