Description

The CE463J is a 4-pole RCCB rated at 63A with 100mA Type A residual current sensitivity. The higher 100mA threshold makes it appropriate for use as a selective or time-delayed upstream device in three-phase TT system installations, where individual downstream circuits have their own 30mA protection.
In a coordinated protection scheme, the CE463J at 100mA sensitivity prevents complete loss of supply when a single downstream 30mA device trips, provided the fault current does not reach 100mA at the incomer. This approach is common in multi-circuit commercial installations.
Operating at 230/400V AC, the CE463J is DIN rail mountable, IP20 rated, and RoHS compliant. It is packaged as 1 piece per unit.
