SEL-487E Transformer Protection Relay
Fault & Thermal Monitoring
Professional rating

Protect and monitor most transformer applications with the powerful SEL-487E. It offers up to five three-phase restraint inputs, three independent restricted earth fault (REF) protection elements, and two three-phase voltage inputs, all with synchrophasors. The SEL-487E limits transformer damage by responding to internal fault conditions in less than 1.5 cycles.
