Residual current circuit breaker 10kA, In=40A, IΔN=0.003A, type G/F, 4-pole. FRCDM-40/4/003-G/F 501260

Residual Current Devices – Protection and Safety of Installations

A residual current device (RCD) is a key element of every modern electrical installation, providing protection for people and equipment against electric shock and the effects of short circuits. The FRCDM-40/4/003-G/F model from Eaton Electric is a four-pole switch with a rated current of 40A and a differential current of 0.003A, designed to operate in TN-S, TT and IT systems. Its construction based on G/F technology guarantees high effectiveness in detecting leakage current to earth, minimizing the risk of hazards.

Functionality and Advanced Features

This residual current device stands out from the competition thanks to the use of a digital display of the leakage current value. This allows for continuous monitoring of the installation status and quick identification of potential problems. Additionally, it is equipped with a remote potential-free contact, which informs about exceeding 30% of the I∆n value – a function particularly useful in monitoring and preventive diagnostics systems. Withstand to short-circuit currents up to 10kA (after overcurrent protection) ensures reliable operation even in difficult operating conditions.

The switch has marine and railway approvals, which confirms its high quality and compliance with stringent safety standards. This makes it an ideal solution for both home and industrial installations, as well as public utility facilities.

• Digital leakage indicator: Enables precise diagnostics of the installation status.

• Remote potential-free contact: Informs about exceeding the leakage threshold, enabling a quick response.

• High short-circuit strength (10kA): Ensures reliable operation even under high loads.

• Marine and railway approvals: Confirm compliance with the highest standards of quality and safety.

• Type G/F: Universal characteristic providing optimal protection in different types of installations.

• Four-pole construction: Allows protection of the entire circuit in one device.

Installation and Application

The installation of the FRCDM-40/4/003-G/F residual current device is simple and intuitive, thanks to standard modular dimensions (4 modules). It finds wide application in:

• Home installations: Protection of lighting circuits, socket outlets and electrical appliances.

• Commercial buildings: Protection of installations in offices, shops, warehouses and other public utility facilities.

• Industrial facilities: Protection of machines and electrical equipment against damage caused by short circuits or leakage currents.

• Marine and railway installations: Due to the approvals held, the switch can be used in the specific conditions of these industries.
