Type A+ RCDs

Type A+ is an extension of the traditional Type A RCD with superior features.

Type A+ RCDs have far higher immunity to nuisance tripping than the traditional Type A RCD and are most suited to areas prone to lightning strikes and electrical surges. Type A+ RCDs will not trip in response to fault currents of several thousand amps for short periods of time and thereby provide a far higher level of immunity to nuisance tripping than an AC or an A Type RCD.

Whilst it is still a relatively new technology and awaits recognition from standards bodies, the demand for Type A+ RCDs is growing because customers want a product with a higher level of immunity to nuisance tripping than that provided by a standard Type A RCD.
