Residual current circuit breaker, 2P, AC, 25A, 30mA, instantaneous F202 AC-25/0.03 2CSF202001R1250

Protection and safety in your electrical installation

This two-pole residual current device (RCD) from ABB's F200 series provides reliable protection for electrical installations and people against electric shock. Designed to protect circuits with a rated current of 25A, it reacts to leakage currents of 30mA, ensuring rapid intervention in the event of insulation failure. AC characteristic means the circuit breaker is sensitive to sinusoidal currents, making it an ideal solution for protecting against the effects of short circuits to earth.

Installation and technical parameters

Installation is on a DIN rail, and the installation depth is 69 mm. The compact width – only 2 modules – allows for efficient use of space in the distribution board. The circuit breaker has a lock that prevents accidental changes to the settings and ensures continuous protection. The rated insulation voltage Ui is 500V, and the rated impulse withstand voltage Uimp is 4kV, guaranteeing resistance to overvoltages. Suitable for operation at temperatures from -25°C to 55°C.

Application and benefits

The F202 AC-25/0.03 circuit breaker is used in residential, commercial and industrial installations. Its instantaneous characteristic ensures quick disconnection of the circuit when a dangerous leakage current is detected. Short-circuit strength at 1kA and withstand current 0.25kA demonstrate its solidity and reliability. Compliance with protection degree IP2X protects against contact with live parts under voltage. The possibility of additional equipment allows you to adapt the circuit breaker to the specific requirements of the installation. This ensures that your installation is safe and compliant with applicable standards.
