Schneider - Easy9 EZ9R03263 2 Pole 63A 30mA RCCB AC Type 230V

The Schneider Electric Easy9 EZ9R03263 Residual Current Circuit Breaker (RCCB) is a reliable 2-pole earth leakage protection device designed to safeguard people and electrical installations against electric shock and earth leakage faults. Rated at 63A with a 30mA earth leakage sensitivity, this RCCB provides fast, dependable protection for residential, commercial, and light industrial single-phase AC electrical systems.

Part of the trusted Schneider Electric Easy9 range, the EZ9R03263 continuously monitors the balance between live and neutral conductors. When a leakage current greater than 30mA is detected, the RCCB disconnects the circuit instantly, helping protect users from electric shock while reducing the risk of electrical fires caused by insulation faults.

This Type AC RCCB is specifically designed to detect alternating sinusoidal residual currents, making it suitable for standard household and commercial electrical installations. Operating at 230VAC, 50Hz, it features a 63A rated current and a 500A rated breaking and making capacity, with a 3kA conditional short-circuit rating when protected by an appropriate Schneider Easy9 MCB.

The compact 2-pole design occupies 4 DIN modules (36mm wide) and installs quickly onto a standard 35mm DIN rail using a clip-on mounting system. A built-in contact position indicator allows quick visual verification of breaker status, while robust tunnel-type terminals accept up to 35mm rigid or 25mm flexible conductors for secure and reliable wiring.

Manufactured to comply with IEC 61008-1 and SANS 767 standards, the Schneider Easy9 EZ9R03263 delivers dependable earth leakage protection for modern electrical installations where personal safety and equipment protection are essential.
