The SIPROTEC  7SJ62 relays can be used for line protection of high and medium voltage networks with earthed (grounded), low-resistance earthed, isolated or compensated neutral point. For motor protection, the SIPROTEC 7SJ62 is suitable for asynchronous machines of all sizes. The relay performs all functions of backup protection
supplementary to transformer differential protection. The relay provides a simple control of the circuit-breaker and automation functions. The integrated programmable logic (CFC) allows the user to implement their own functions,   e. g. for the automation of switch gear (interlocking). The user is also allowed to generate user-defined messages.
The flexible communication interfaces are open for modern communication architectures with control systems.The  7SJ62 unit is a numerical protection relay that also performs control and monitoring functions and therefore
supports the user in cost-effective power system management, and ensures reliable supply of electric power to the customers. Local operation has been designed according to ergonomic criteria. A large, easy-to read display was a major design aim.
