RCCBs Type 'AKV'
Type A KV RCCBs are designed to withstand supply transients up to 3kA, to reduce nuisance tripping associated with some load characteristics, such as EV chargers, lighting and SPDs. Type AKV devices must not trip when subjected to an 8/20┬Ás 3kA transient or short duration leakage currents flowing for <10ms associated with capacitor charging, EV and machines. AKV devices still meet the tripping requiremenst for General/Non-delay RCCBs to EN61008-1, required for additional protection (30mA) and fire protection (300mA).
See Appendix 3 Table 3A of the current Wiring Regulations.
Selection in the same way as standard RCCBs Available in 2 and 4 pole versions from 16-125A with various sensitivities, see below:- View Technical Data for all RCCBs
