Porduct Overview

What types of circuits can AFDD be used on?

In AC single-phase circuits not exceeding 230V, that includes ring circuits, radials etc. Where used, AFDD shall be placed at the origin of the circuit to be protected.

EKL17-40AFD devices are a single module device which fits the existing busbar system of the existing arrangement. The device offers protection against overcurrent, short circuit, earth leakage and arc fault all in one device and are available in B & C Curve variants. It can direct replacement RCBO in existing consumer units.

Limit values of operating criteria for AFDD at low arc currents up to 63 A (IEC62026)

Limit values of break time for Ue 230V AFDD

Test arc current (r.m.s.values)	Max breaking time
2.5A	1S
5A	0.5S
10A	0.25S
16A	0.15S
32A	0.12S
63A	0.12S

Note:

1. The test arc current is the expected current before ignition occurs in the test circuit.

2. Low arc currents can occur due to insulation faults phase to earth or series arcing.
