Sepam Series 20 is a protection relay range designed for standard distribution system applications. It provides 7 types of digital current or voltage protection for standard distribution systems, each one dedicated to a single application. The communication interface is enabled with 2 wire RS485 Modbus port protocol. The rated supply voltage is 12 VDC and 24 VDC. The supply current is 16 mA for receiving mode and 40 mA for maximum in sending mode. This device can be fixed on DIN rail. Mechanical dimensions are 88 mm in height, 72 mm in width and 30 mm in depth.
