Residual current circuit breaker, 2P, AC, 40A, 100mA, instantaneous F202 AC-40/0.1 2CSF202001R2400

Safety and reliability in your electrical installation

This two-pole residual current device (RCD) from ABB, with a rated current of 40A and a tripping current of 100mA, is a key element ensuring the protection of people and equipment against electric shock and the effects of short circuits. The use of AC characteristics makes it particularly effective in detecting sinusoidal leakage currents, typical of most household and industrial loads.

This circuit breaker is used in electrical installations with a voltage of 230V, where high effectiveness of shock protection is required. Its compact design – it occupies only 2 modules on a DIN rail – allows for efficient use of space in the distribution board. Solid construction and high short-circuit strength (1 kA) guarantee long-lasting and trouble-free operation.

• Protection against electric shock: Detects even small leakage currents, minimizing the risk to life.
• Wide application: Ideal for protecting lighting circuits, sockets in wet rooms (bathrooms, kitchens) and electrical appliances.
• Easy installation: Designed for quick and easy mounting on a standard DIN rail.
• Locking: Integrated lock prevents accidental disconnection of the circuit breaker by the operator.
• Wide temperature range: Enables operation in difficult environmental conditions (-25°C to +55°C).
• High quality workmanship: Guarantees reliability and long service life.

The circuit breaker meets strict safety standards, including IP2X protection, which means protection against touching with a finger and protection against the ingress of solid objects with a diameter of more than 12.5 mm. The cross-section of the single-wire connecting cable up to 25 mm² ensures compatibility with most electrical installations. The rated impulse withstand voltage of 4 kV provides additional protection against overvoltages. Thanks to this, you can be sure that your installation is safe and protected against potential failures.
