RCCB

ALFR RCCB

The ALFR RCCB provides rated currents ranging from 16A to 100A, with rigorous endurance testing and precise breaking times for different leakage types. It features a modern design, user-friendly connections, and high surge resistance up to 5kA. The selective S Type prevents nuisance tripping, making it suitable as a main breaker or for use with surge protectors.

Product Details

Product Descriprion

The ALFR RCCB series supports multiple rated currents ranging from 16A to 100A, designed for residential, commercial, and industrial distribution systems. It features an electromagnetic release mechanism and meets EN/IEC 61008-1 standards. The Type S model incorporates a minimum 40ms time delay to prevent nuisance tripping, making it suitable as a main switch or for use with Class II surge protectors.

Featuring a contemporary design, the product supports conductor connections up to 35mm² and can be securely mounted on DIN rails. A dual-color contact position indicator (red for closed, green for open) enhances operational safety, and all models are capable of withstanding current surges of up to 5kA. Its user-friendly wiring, compatible with busbars and pin-type terminals, and IP20 protection rating ensure reliable performance in diverse environments.

Performance includes rigorous endurance testing (on-load/off-load operating cycles) and precise breaking time requirements, tailored to the leakage type and current values. The Type S breaker provides selective protection, significantly reducing unnecessary power outages while meeting automatic disconnection time requirements of 0.2s or 0.4s, delivering essential reliability for demanding residual current protection scenarios.
