Product details

Overview

The EZ9R03463 is a 4-pole Easy9 RCCB rated at 63 A with 30 mA earth-leakage sensitivity, AC type, for 400 V 50 Hz networks. It complies with IEC 61008-1 and SANS 767. Instantaneous trip, no time delay.

Selection vs 2-pole variants

Compared to the 2-pole EZ9R14225 (25 A, 230 V), the EZ9R03463 doubles the poles to 4 and more than doubles the current to 63 A at 400 V, suiting three-phase main incomers rather than single-phase subcircuits. Terminal capacity is also larger: 35 mm² rigid vs 25 mm².
