Residual current circuit breaker, 4P, A, 63A, 300mA, selective F204 A S-63/0.3 2CSF204201R3630

Safety and reliability in your installation

The ABB F204 A S-63/0.3 residual current circuit breaker (RCCB) is a key element ensuring the protection of people and equipment in electrical installations. This four-pole device with a rated current of 63A and a sensitivity of 300mA (Type A) effectively reacts to leakage currents, minimizing the risk of electric shock and preventing damage. Its selectivity allows for coordinated operation with other circuit breakers in the circuit, ensuring precise location and isolation of the damaged section of the installation.

Design and installation

The circuit breaker is designed for mounting on a DIN rail, which simplifies and speeds up installation. Compact dimensions (width 4 modules, depth 69 mm) allow for efficient use of space in the distribution board. The solid construction guarantees durability and resistance to mechanical damage. Terminal block locking provides additional safety when connecting wires with a cross-section of 25 mm². The device meets the IP2X degree of protection standard, which means protection against touching with a finger and solid objects larger than 12.5 mm.

Application and benefits

This RCCB is used in residential, commercial and industrial installations. Its high short-circuit strength (1 kA) and surge current withstand (5 kA) guarantee reliable operation even in difficult operating conditions. The rated impulse withstand voltage Uimp is 4 kV, which provides additional safety in the event of overvoltages. Thanks to selective protection, it is possible to precisely disconnect only the damaged circuit, without interrupting the power supply to the entire installation – this saves time and repair costs. The device operates in an ambient temperature range from -25°C to 55°C, making it a universal solution for various working environments. The possibility of additional equipment allows the circuit breaker to be adapted to the specific requirements of a given application.
