Residual current circuit breaker, 4P, A, 40A, 100mA, selective F204 A S-40/0.1 2CSF204201R2400

Safety and reliability in your electrical installation

This four-pole residual current circuit breaker (RCCB) from the F200 series is a key element ensuring the protection of people and equipment against electric shock and the effects of short circuits and overloads. Designed by ABB, it combines high efficiency with compact dimensions – it occupies only 4 modules on a DIN rail. This is an ideal solution for both new installations and modernization of existing ones.

Characteristics and application

The F204 A S-40/0.1 circuit breaker is characterized by a rated current of 40A and a residual current sensitivity of 100mA (type A). This means that it is particularly effective in detecting leakage currents that can occur, for example, as a result of insulation damage or direct contact with live conductors. The use of type A means that the circuit breaker reacts to both DC and AC currents, which increases the scope of protection. Thanks to selectivity, it is possible to coordinate the operation with other circuit breakers in the installation, minimizing the risk of unnecessary disconnection of the entire network in the event of a failure on one circuit.

Key features and benefits

• High reliability: Made of high-quality materials, guarantees long-lasting and trouble-free operation.
• Fast response: 100mA sensitivity ensures quick disconnection of the circuit in the event of a leakage current, minimizing the risk of electric shock.
• Compact dimensions: Occupies only 4 modules on a DIN rail, which facilitates installation even in tight switchboards.
• Wide range of applications: Ideal for protecting lighting circuits, socket outlets and electrical appliances in residential and commercial buildings.
• Selectivity: Enables coordinated protection of the electrical installation, minimizing downtime caused by failures.
• Safety: With a lock preventing accidental switching on of the circuit breaker after switching off due to a failure.
• Resistance to external conditions: Adapted to operate at temperatures from -25°C to +55°C, which ensures reliability even in difficult environmental conditions.
• DIN rail mounting: Standard mounting facilitates installation and replacement of the device.

Additional technical information: rated voltage 400V AC, insulation rated voltage Ui 500V and impulse withstand voltage up to 5kA confirm the high quality and safety of this residual current circuit breaker. The cross-section of the connectable single-wire conductor up to 25 mm² ensures compatibility with most electrical installations. Protection degree IP2X protects against finger contact and solid objects larger than 12.5 mm.
