Residual current circuit breaker, 4P, A, 40A, 300mA, selective F204 A S-40/0.3 2CSF204201R3400

Safety and reliability in your electrical installation

The ABB F204 A S-40/0.3 residual current circuit breaker is a key element ensuring the protection of people and equipment against electric shock and the effects of short circuits and overloads. Designed for demanding applications, this four-pole circuit breaker combines high efficiency with selectivity, which translates into the reliability of the entire system.

Protection tailored to your needs

This model, with a rated current of 40A and a sensitivity of 300mA, is ideal for protecting electrical circuits in residential, commercial and industrial buildings. Characteristic A provides a quick response to leakage currents, minimizing the risk of electric shock. Selectivity allows for precise disconnection of the damaged circuit without interrupting the power supply to the remaining parts of the installation – this is particularly important in complex electrical systems. This circuit breaker also has a lock that prevents accidental switching on after switching off due to a failure.

Installation and technical parameters

The residual current circuit breaker is mounted on a DIN rail, which facilitates its installation and replacement. Its compact dimensions (width 4 modules, depth 69 mm) allow for efficient use of space in the switchgear cabinet. Made of high-quality materials, it meets safety standards and withstands a rated voltage of 400V and an impulse voltage of 4kV. The impact current resistance is as high as 5kA, which guarantees its reliable operation even in difficult operating conditions. Designed to operate in an ambient temperature from -25°C to 55°C. The possibility of additional equipment increases the functionality of the device and allows it to be adapted to the specific requirements of the installation. The cross-section of the connected single-wire conductor is 25 mm².

High resistance to interference: Pollution degree 2 ensures stable operation even in environments with increased pollution levels.

Versatile application: Suitable for AC circuits with a rated voltage of 400V.

Safety of use: Has a degree of protection IP2X, which protects against touching live parts under voltage.

Quick identification: Clear markings facilitate identification and servicing of the device.

Compliance with standards: Ensures compliance with applicable electrical safety standards.
