Residual current circuit breaker, 4P, A, 40A, 30mA, instantaneous F204 A-40/0.03 2CSF204101R1400

Safety and protection in your installation

Residual Current Device (RCD) F204 A-40/0.03 is a key element ensuring the safety of people and electrical installations. The device, manufactured by the renowned ABB company, effectively protects against electric shock and damage caused by short circuits to earth. It is a four-pole switch with a rated current of 40A and a sensitivity of 30mA, which means a quick reaction to dangerous leakage currents.

Functionality and application

The switch is designed for use in electrical installations with a voltage of 400V AC. Its construction based on characteristic A provides protection against both sinusoidal and pulsating DC currents, which is particularly important in modern installations with electronic devices. It will work in residential, commercial and industrial buildings. Mounting is done on a DIN rail, which facilitates integration with the existing electrical infrastructure. The width of the device is 4 modules (70mm), which allows for efficient use of space in the switchgear cabinet.

Key features and benefits

• High reliability: ABB F200 series circuit breakers are known for their solid construction and long service life.
• Fast reaction: 30mA sensitivity guarantees quick disconnection of the circuit in the event of a leakage current, minimizing the risk of electric shock.
• Protection against various types of currents: Characteristic A provides protection against sinusoidal and pulsating DC currents, increasing the range of applications.
• Easy installation: DIN rail mounting makes installation easier and faster.
• Compliance with standards: The switch meets the requirements of IEC/EN 61008 standards, ensuring safety and compliance with regulations.
• Durability: Withstands impulse currents up to 0.25kA and short-circuit currents up to 1kA, ensuring stable operation in difficult conditions.
• Wide operating temperature range: The ability to operate in a temperature range from -25°C to +55°C makes it suitable for various environments.
• Locking: It has a lock preventing accidental switching on of the switch after it has been switched off by the operation of the residual current protective device - additional protection during maintenance work.
