PROTEK RCBO Type B Curve 10kA 20 AMP 30mA Single Module RCBO1-30/B20

Protek’s single module RCBOs in B curve. Protek’s RCDs are Type AC.

The RCBO’s are rated at 10kA and, as with the MCBs from which it was developed, it has Positive Contact Indication.

Tripping is ensured for residual sinusoidal current alternating currents whether the fault is suddenly applied or is a slow rising fault.

To offer this degree of protection the RCD elemt of the device must have a sensitivity or 30mA or less and must trip out with a sinsoidal current of 150A in less than 40mS.
