Residual current circuit breaker, 2P, A, 40A, 30mA, instantaneous F202 A-40/0.03 110V 2CSF202199R1400

Residual Current Device – Protection and Safety of the Installation

This two-pole residual current device (RCD) from ABB's F202 series is a key element ensuring safety in every electrical installation. Designed to protect people and equipment from the effects of leakage currents, it effectively reacts to irregularities, minimizing the risk of electric shock and equipment damage. This model, with a rated current of 40A and a sensitivity of 30mA, is perfect for circuits requiring high protection efficiency.

Functionality and Application

The F202 A-40/0.03 circuit breaker is characterized by instantaneous type A tripping, which means it quickly responds to sinusoidal and pulsating DC leakage currents. This makes it ideal for protecting circuits powering electronic devices, LED lighting, or general-purpose sockets. DIN rail mounting (2 module width) simplifies installation and integration with existing distribution boards. The locking mechanism prevents accidental switching on, increasing safety during maintenance and repairs.

Key Features and Benefits

• High Reliability: Made of high-quality materials, ensuring long-lasting and trouble-free operation.
• Fast Response: Instantaneous type A characteristic guarantees quick circuit disconnection in case of a leakage current.
• Versatility: Suitable for operation in AC installations with a voltage of 230V and a frequency of 50/60Hz.
• Easy Installation: Standard DIN rail mounting simplifies installation and replacement.
• Short-Circuit Protection: Short-circuit strength of 1kA provides protection against the effects of short circuits in the installation.
• Wide Operating Temperature Range: The ability to operate at temperatures from -25°C to 55°C allows it to be used in various environmental conditions.
• Expandability: Compatibility with additional accessories allows the circuit breaker to be adapted to specific installation needs.
• Safety of Use: Equipped with a lock preventing accidental switching on during maintenance work.
