Residual current circuit breaker, 4P, A, 40A, 300mA, instantaneous F204 A-40/0.3 2CSF204101R3400

Safety and reliability in your electrical installation

The ABB F204 A-40/0.3 residual current circuit breaker (RCCB) is a key element ensuring the protection of people and equipment in electrical installations. Designed to work with AC circuits, it effectively detects and interrupts leakage currents, minimizing the risk of electric shock and equipment damage. This four-pole circuit breaker with a rated current of 40A and a sensitivity of 300mA is characterized by instantaneous tripping, which guarantees a quick response in emergency situations.

Construction and installation

The circuit breaker is extremely easy to install thanks to the standard mounting method on a DIN rail. It occupies 4 modules in width, allowing for efficient use of space in the distribution board. The solid construction and high-quality materials ensure long-lasting and trouble-free operation. Terminal locking additionally increases safety during installation and maintenance. The cross-section of the connectable solid conductor up to 25 mm² allows connection of cables of different thicknesses, adapting to the specifics of the installation.

Application and benefits

The F204 A-40/0.3 residual current circuit breaker finds wide application in both domestic and industrial installations. It is ideal for lighting circuits, electrical outlets and for powering electrical devices exposed to insulation damage. Its high short-circuit strength (1 kA) provides protection even in the event of large voltage surges. The rated impulse withstand voltage of 4 kV additionally protects against the effects of sudden voltage spikes. Thanks to this, you can be sure that your installation is safe and reliable. Additionally, the possibility of expansion with accessories allows you to adapt the circuit breaker to individual needs.
