Residual current circuit breaker 4-pole PFIM-40/4/003-G-MW 235453

### Residual Current Device – Reliable Installation Protection

This four-pole residual current device from Eaton, model PFIM-40/4/003-G-MW, is a key element of every safe electrical installation. It provides protection against the effects of leakage currents, minimizing the risk of electric shock and equipment damage. This is particularly important in residential, commercial, and industrial environments.

### Functionality and Installation for Professionals and Users

The circuit breaker is designed to operate in three-phase circuits with a voltage of 400V and a rated current of 40A. Installation is done on a standard DIN rail, which greatly simplifies and speeds up the installation process. The use of lift and busbar terminals (from above and below) allows for flexible connection of wires with a cross-section from 1.5 mm² to 16 mm² (multi-stranded) or 1.5 mm² to 35 mm² (solid). The mechanical lock provides additional safety when working with the device.

### Characteristics and Additional Possibilities

The circuit breaker is characterized by a high shock current resistance – up to 3 kA, and its short-circuit strength is 10 kA. The short-circuit tripping effectively reacts to sudden current increases, protecting the circuit from overload. Additionally, the ability to add auxiliary contacts, undervoltage releases, and a reclosing device expands the functionality of the device and allows it to be adapted to the specific needs of the installation. The power supply direction is arbitrary, and the optical contact position indicator makes it easier to control the device status.

* **Versatility:** Wide range of applications – from single-family homes to industrial facilities.

* **Safety:** Protection against electric shock and equipment damage thanks to high sensitivity to leakage currents (0.03 A).

* **Easy installation:** Quick and easy installation on a standard DIN rail using convenient lift and busbar terminals.

* **Flexibility:** Possibility to expand functionality by adding accessories (auxiliary contacts, releases).

* **Durability:** Made of high-quality materials ensuring reliable operation in a wide range of ambient temperatures (-25°C to +60°C).

* **Compliance with standards:** Meets the required safety standards (IP20).

The PFIM-40/4/003-G-MW circuit breaker is an investment in the safety and reliability of your electrical installation. Its solid construction and rich equipment make it the ideal choice for both professional installers and demanding end-users.
