General characteristics of SR2 Enclosures

The range of SR2 enclosures is a complete offer of monobloc enclosures for constructing small and medium-sized electric
automation, switching and control switchboards.

The SR2 enclosures come from the experience ABB has The SR2 enclosures have also passed the control required to
