Description

The CFA580W is a 2-pole (1P+N) RCCB rated at 80A with 300mA Type A residual current sensitivity. It is intended for use as a selective incomer or sub-main device in single-phase TT system installations where downstream circuits have individual 30mA protection and a higher-sensitivity upstream device is required.
The 300mA threshold allows the CFA580W to provide earth fault back-up protection without tripping unnecessarily from the accumulated leakage of several downstream 30mA RCDs or RCBOs. It is suited to larger residential or light commercial single-phase main distribution.
Operating at 230V AC, the device is DIN rail mountable and compact in design. It is IP20 rated and RoHS compliant. Packaged individually as 1 piece per unit.
