The technical characteristics of interlocked-switch socket outlets have been carefully tailored to the intended end use of the product, and comply in full with EN60309-1 (IEC309-1) and EN60309-2 (IEC309-2) standards. They satisfy the most diverse electrical installation requirements, while improving the degree of safety and reliability in these installations.
The use of interlocked-switch socket outlets is growing steadily. By preventing the insertion and extraction of the plug when alive, connection accurs only under the best circuit conditions and therefore avoids any possibility of contacts giving off sparks which might cause danger to life and property.
