Residual current circuit breaker EFI-P2 A 25/0.3 002061131

Reliable protection of electrical installations

Residual Current Device (RCD) EFI-P2 A 25/0.3 is a key element ensuring safety in every electrical installation. It is used to protect against electric shock, both in the case of direct and indirect contact with live parts. Additionally, it protects devices from damage caused by overload or short circuit, minimizing the risk of fire. This is particularly important in TN-S, TN-C-S, TT and IT networks, where the correct operation of RCDs is crucial for the safety of users and equipment.

Functionality and technical parameters

This two-pole (2P) switch with a rated current of 25A and sensitivity A is designed to operate in AC networks with a voltage of 240V and a frequency of 50/60Hz. Its construction based on type A technology means that it reacts to both alternating residual currents and pulsating DC currents – which increases the scope of protection. The short-circuit strength at 10kA guarantees reliable operation even in the event of serious disturbances in the network. Mounting is on a DIN rail, and the width of the device is 2 modules – which facilitates integration with existing switchboards. The terminals allow connection of multi-strand and solid core wires with a cross-section of 25mm².

Ease of use and installation

The switch is equipped with a test button that allows for regular checking of its functionality. The contact position indicator makes it easy to identify the device status (ON/OFF), and the secured terminals minimize the risk of accidental contact with live parts. The possibility of sealing the lever provides additional protection against unauthorized changes to the settings. The terminal design allows the use of insulated busbars, which simplifies installation and improves the aesthetics of the installation. Thanks to this, both installers and end users can count on convenience and safety of use.
