Acti 9 Super Immunised (SI) RCDs:
Ideal for polluted environments, the Acti 9 Super Immunised range of RCDs provide increased immunity from electrical interference. They have been designed to maintain optimum safety and continuity of supply in installations with harmonic disturbances.
> Increased Safety
> Improved continuity of supply
> High Frequency rejection filter
> Energy storage circuit to distinguish between a transient and a constant leakage
> Checking circuit, to validate or disable the tripping order in view of the information generated by the filters
> Increased maximum loads over standard RCDs
