ABL SURSUM FIP2303 Residual Current Circuit Breaker

The ABL SURSUM FIP2303 residual current circuit breaker is a two‑pole RCCB rated for 40 A with a 30 mA residual‑current sensitivity, designed for 230/400 V electrical systems. Often catalogued as RP2303, this Type A device trips on leakage between live and neutral, providing protection against electric shock and helping prevent fires from insulation faults. Its 2‑pole construction ensures simultaneous disconnection of both conductors to fully isolate a circuit, making it suitable for installation in distribution boards and consumer units in residential or light commercial wiring. Typical applications include circuits feeding outlets, lighting, and equipment where leakage protection is required by safety standards, with a 30 mA sensitivity that balances prompt fault detection with nuisance‑tripping avoidance. The FIP2303/RP2303 is intended for standard 230 V AC mains and uses a 40 A nominal current, aligning with common protective device configurations in European installations.
