The Sepam Series 40 relay is designed for mid-range loads and sources. It features directional over current protection for dual mains and ties and closed loop feeders for improved coordination with adjacent protection, 16 seconds of fault recording configurable for mulitple captures and retention of the last 200 time-tagged alarms for enhanced fault analysis.
The Sepam Series 80 relay was designed for one purpose - to meet or exceed the protection requirements of the harshest, most demanding industrial locations - bar none. It can be integrated into virtually any electrical equipment; it has expanded logic equation capabilities that provide increased customization of control and protection.
