Residual current circuit breaker, 2P, A, 40A, 30mA, instantaneous F202 A-40/0.03 2CSF202101R1400

Protection and safety in your electrical installation

This two-pole residual current device (RCD) from ABB's F202 series is a key element ensuring safety in electrical circuits. Designed to protect people and installations from the effects of leakage currents, it effectively detects and interrupts the circuit in the event of insulation failure. Its operation is based on the principle of rapid response to the difference in currents in the phase and neutral conductors, which minimizes the risk of electric shock.

This circuit breaker is characterized by a rated current of 40A and a sensitivity of 30mA (type A), which means it is ideal for protecting circuits with higher power consumption, requiring high precision in detecting leakage. The instantaneous tripping characteristic ensures a quick response in hazardous situations. Mounting is on a DIN rail, which facilitates integration with existing electrical infrastructure.

Features and application

The F202 A-40/0.03 RCD finds wide application in electrical installations in residential, commercial and industrial buildings. It is perfect for protecting lighting circuits, socket outlets and electrical appliances exposed to moisture. Thanks to its compact dimensions (2 module width) it does not take up much space in the distribution board.

• Protection against electric shock: Fast detection and disconnection of the circuit in the event of leakage currents minimizes the risk to users.
• Installation protection: Protects against damage caused by overload or short circuit to earth.
• Versatility: Suitable for protecting various types of circuits – lighting, socket outlets, electrical appliances.
• Easy installation: DIN rail mounting ensures quick and trouble-free installation.
• High reliability: ABB brand product guarantees high quality workmanship and long-term operation.
• Durability: Short-circuit strength at the level of 1kA ensures resistance to sudden current surges during short circuits.
• Wide operating temperature range: The ability to operate in a temperature range from -25°C to 55°C makes it suitable for various environmental conditions.

In addition, the circuit breaker has a mechanical lock that prevents accidental switching on after switching off due to a failure – this is an additional safety feature for the installer and end user. Compliance with IEC EN 61008 confirms its safety and compliance with applicable standards.
