Product details

RCCB for the Easy9 range — 63 A, 300 mA, Type AC

The Schneider Electric EZ9R64263 is a 2-pole residual current circuit breaker (RCCB) from the Easy9 range, rated 63 A with 300 mA earth leakage sensitivity. The 300 mA sensitivity suits sub-distribution boards feeding multiple final circuits, where nuisance tripping from cumulative leakage is a concern. Instantaneous trip time means no intentional delay — fault current clears as soon as the threshold is crossed.

Tunnel-type terminals top and bottom accept 1…25 mm² rigid or 1…16 mm² flexible cable; tightening torque 2.5 N·m. IP20 finger-safe terminals are standard for enclosure use — the RCCB lives inside a distribution board, not exposed to washdown or outdoor moisture.
