Industrial transformer and feeder protection device

Protection that stands firm when the grid gets tough

Sepam Series 60 brings rugged, multifunctional protection for feeders, motors, transformers, generators, and capacitors — backed by modular I/O, deep diagnostics, and industrial-grade endurance.

Harsh networks break weak protection

Old relays fail under heat, dust, noise, and vibration — lose CT/VT upervision, miss early earth faults, and leave operators blind during disturbances. The result? Slow clearing, wrong trips, and zero clarity when things go wrong.

Weak EF detection

No harsh-site resilience

Missing CT/VT checks

Shallow fault records

Rigid schemes

Meet Sepam Series 60 — built for the realities of industrial power

Sepam 60 delivers ANSI-grade protection wrapped in a tough, conformal-coated design built for extreme sites. It covers overcurrent, directional earth fault, SEF, REF, thermal, differential, overpower/underpower, motor start, recloser control, synchro-check, and breaker failure. With modular I/O, flexible logic, strong metering, fast COMTRADE records, and IEC 61850-ready networking, Sepam 60 becomes the protection, control, and monitoring core of any substation bay.
