In automation LEGRAND conductors inside and outside of the clamping contacts are copper surface. Also good quality and are aligned with ABB.

In elektroavtomatah DEC clamp contacts the metal. Operate normally, provided they are family. Disable is a little slower than ABB and LEGRAND.
Electroautomatika and other constituent elements of the wiring in the apartment must be as reliable. After all, it depends, first and foremost, the safety of your home. Buy automatics only necessary in specialized stores, where, if necessary, may confirm the quality of the product specific documents.
