Description

The CF263J is a 2-pole RCCB rated at 63A with 300mA Type A residual current sensitivity. This high-sensitivity threshold is intended for fire protection rather than personal protection, making it suitable for use as a selective incomer device on single-phase installations with downstream 30mA protection on individual circuits.
In TT system installations, a 300mA incomer RCCB in conjunction with 30mA RCBOs on each final circuit provides a coordinated protection scheme. The CF263J acts as back-up protection without tripping prematurely due to accumulated leakage current from multiple circuits.
The device operates at 230V AC and is DIN rail mountable. It is IP20 rated and RoHS compliant. Packaged as 1 piece per unit.
