Siemens SIPROTEC 7SJ8041-5EC90-3FC0 L0A Overcurrent Protection Relay
Siemens SIPROTEC Overcurrent Protection Relay with PROFIBUS DP Slave.
The Siemens 7SJ8041-5EC90-3FC0 L0A is an overcurrent protection relay housed in a 1/6 19" format. It features 4 current inputs (IPH=1A/5A, IE=1A/5A), 3 voltage inputs, 7 binary inputs, and 8 binary outputs (2 changeover), plus 1 live status contact.
This advanced relay offers comprehensive protection, including phase overcurrent (50/51), ground fault protection (50N/51N, IEE>, IEE>>, IEEP), and overload protection (49). It includes a PROFIBUS DP Slave communication port (Port B) for seamless integration into industrial networks. The unit supports rated auxiliary voltages of DC 60V/110V/125V/220V and AC 115V/230V.
Ideal for complex power systems, this relay provides reliable protection and advanced communication capabilities. Stanlo Automation, your veteran-owned source for industrial automation parts, offers this Siemens relay for your critical applications.
