RCBOs Type AC

Type AC residual current

Regulation 531.3.3 Tripping on:

  • 50Hz sinusoidal AC

Note: type AC RBOs are not suitable for use in circuits powering electronically controlled equipment.

Type AC RCBOs must not be connected upstream of Type A, F, B or EV RCDs.

Application Notes:
a) 1 pole + N RCBOs are not suitable for single phase IT systems.
b) Center tapped (CT) transformer supplies for fixed equipment:
Use 2 pole RCCB + 2 pole MCBs. For 110V supplies, use 110v RCCBs.

3 pole + N 400V RCBOs are available in Type A
