CBRs Type A

Type A residual current

Regulation 531.3.3 Tripping on:

  • 50Hz sinusoidal AC
  • Pulsating DC
  • Pulsating DC superimposed on smooth DC < 6 mA

Note: Type A RCDs do not detect smooth DC. For circuits incorporating inverters – use DFL8 Type B.

RCD selection and application CBRs accessories Technical data

30 mA versions have non-adjustable RCD characteristics.
0.3 < 3 amp versions have adjustable RCD characteristics
