Residual current circuit breaker EFI-P4 A 25/0.03 002061511

Safety first – Residual Current Device EFI-P4 A 25/0.03

This four-pole residual current device from ETI POLAM 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. Designed to operate in AC networks with a voltage of 415V and a frequency of 50/60Hz, it offers reliable protection in a wide range of applications.

The EFI-P4 A 25/0.03 RCD is characterized by a rated current of 25A and sensitivity A, which means it reacts to both alternating currents and pulsating direct currents. This makes it ideal for protecting circuits powering various types of receivers, including those sensitive to interference. Its short-circuit strength of 10kA guarantees resistance to sudden current surges, and its compact dimensions (width 4 modules, depth 68mm) make it easy to mount on a DIN rail.

Functionality and installation

The RCD has been designed with ease of installation and use in mind. The ability to mount additional accessories, such as auxiliary contacts or release devices, allows it to be adapted to the specific needs of a given installation. The connection terminals are adapted to conductors with a cross-section from 1 to 25 mm², both solid and stranded. Additionally, the protection of the terminals against contact under voltage increases safety when working with the device. The version with the neutral pole N located on the left side facilitates cable organization.

The "Test" button allows for regular checking of the RCD's functionality, and the contact position indicator helps to quickly identify its status (ON/OFF). The RCD has a protection rating of IP20, which means protection against touching with a finger and solid objects larger than 12.5 mm – sufficient for most standard indoor applications. This makes it a solution for both professional installers and end-users looking for reliable protection in their home or business.
