Arc Fault Detection Device(AFDD) CJAF1

Short Description:

CJAF1 Single module AFDD/RCBO with switched N pole provides the highest levels of protection for the installation and its users. It combines the function of a residual current operated device for earth leakage detection, overcurrent protection for short-circuit and Arc fault detection for both parallel and series arcs. The device is intended to reduce the risk of fires by ignition from electrical sources. Because of one module width, it does not require larger consumer units and AFDD can easily be retro fitted into existing installations.

Operation and Display

■LED Indication:
□After tripping under a fault condition the fault status indicator will show the fault nature according to the table opposite.
□LED flashing sequence repeats every 1.5sec for next 10 sec after powering up

■Series Arc Fault:
□1 Flash – Pause – 1 Flash – Pause – 1 Flash

■Parallel Arc Fault:
□1 2 Flashes – Pause – 2 Flashes – Pause – 2 Flashes

■Over Voltage Fault:
□3 Flashes – Pause – 3 Flashes – Pause – 3 Flashes

■Self-Test Fault:
□1 Flash – Pause -1 Flash – Pause -1 Flash (At Double Rate)
