Residual current circuit breaker EFI-P2 A 80/0.3 002061134

Safety and protection in your electrical installation

Residual Current Device (RCD) EFI-P2 A 80/0.3 is a key element ensuring the safety of using the electrical installation, protecting against electric shock and potential fire hazards resulting from insulation damage. The device is intended for use in TN-S, TN-C-S, TT and IT networks, where the neutral and earth conductors are separated.

This two-pole RCD with a rated current of 80A and sensitivity A effectively reacts to leakage currents, providing protection for both people and electrical devices. Its mounting on a DIN rail is quick and intuitive, which will be appreciated by professional installers. Thanks to its compact dimensions (width of 2 modules and depth of 68 mm), it can be used even in limited space of the switchboard.

Functionality and technical parameters

The RCD is characterized by high resistance to surge current – as much as 0.4 kA – which translates into its reliability in emergency situations. The rated insulation voltage Ui is 440V, and the rated differential current is 0.3A. Adapted to operate at frequencies of 50/60 Hz, it meets the requirements of modern electrical installations. It accepts multi-wire and solid-core wire cross-sections in the range of 25 mm², providing flexibility in choosing the appropriate cables.

It is worth noting the conditional short-circuit strength of 10 kA – a parameter important for ensuring the correct operation of the RCD in the event of a short circuit in the installation. The degree of protection IP20 guarantees protection against accidental contact, but does not protect against the action of water.

Application and benefits

The EFI-P2 A 80/0.3 RCD finds wide application in both home and industrial installations. It is ideal for securing circuits with higher loads, where high sensitivity to leakage currents is required. Thanks to its design and technical parameters, it provides effective protection against electric shock and minimizes the risk of fires caused by damage to cable insulation. By choosing this RCD, you are investing in your own safety and that of your customers.
