Residual current circuit breaker, 2P, A, 40A, 100mA, selective F202 A S-40/0.1 2CSF202201R2400

Residual Current Circuit Breaker – Safety and Selectivity in One

This two-pole residual current circuit breaker from ABB's Standard F202 A S-40/0.1 series is a reliable solution providing comprehensive protection for electrical installations. Designed for both installers and users, it combines high performance with selectivity, minimizing the risk of unnecessary circuit tripping. Rated current of 40A and a residual current sensitivity of 100mA make it an ideal choice for protecting various loads.

Construction and Application

The circuit breaker is designed for mounting on a DIN rail, making installation quick and easy. Its compact dimensions (2 module width) allow for efficient use of space in the distribution board. The device protects against the effects of short circuits, overloads and, above all, against electric shock caused by leakage currents. Selectivity means that in the event of a fault, only the damaged circuit will be switched off, while the rest will continue to operate without interruption – this is particularly important in more complex installations. Made of high-quality materials, it ensures long-lasting and trouble-free operation in a wide range of ambient temperatures (-25°C to +55°C).

Key Advantages and Parameters

• Selectivity: Provides protection without unnecessarily switching off the entire system – an ideal solution for complex installations.
• Type A: Protects against pulsating and sinusoidal leakage currents, ensuring safety for people and equipment.
• Rated current 40A: Suitable for most standard household and industrial circuits.
• Sensitivity 100mA: Reacts quickly to dangerous leakage currents, minimizing the risk of electric shock.
• Breaking Capacity: Withstand current to 5kA guarantees effective protection in the event of short circuits. Short-circuit withstand (Icw) is 1kA.
• Safety: Features a lock preventing accidental switching on after switching off due to a fault.
• Mounting: Easy mounting on a DIN rail – saving time and installation costs.
• Width: Occupies only 2 modules in the distribution board – optimal use of space.
• Rated voltage: 230V AC and insulation voltage of 500V ensure safe operation of the device.
• IP2X protection degree: Protection against touching with a finger and solid objects with a diameter greater than 12.5mm.

This circuit breaker complies with safety standards and has a high level of reliability, making it an ideal choice for demanding users who value safety and comfort.
