The SIEMENS 7SJ / 7SJ60 catalog comprises numerical overcurrent and overcurrent-time protection relays, often designated as SIPROTEC 7SJ600. These relays provide overload and unbalanced-load protection, incorporating binary input voltage ranging from 24 to 250V and isolated RS485 interfaces. Rated currents vary, and some models include rated auxiliary voltage for built-in converters.
