Quality design ensures resistance to premature failure through corrosion, fatigue, shock or vibration.

Nuisance-free operation when subject to high in-rush currents or transients, allowing ratings to be closely matched to the needs of the system and enabling the most efficient sizing of wiring and components.

The technical capabilities enable homes and buildings to use electrical in a much more sensible manner by better managing energy use.

Unlike fuses, no need for spares. Risks of using temporary inappropriate substitutes are eliminated, and warranty costs are reduced.

Positive physical interruption of the circuit is ensured. There is no risk of equipment remaining live. Low leakage currents are eliminated.

Internationally approved, avoiding the need for different models for different national standards.
