The SE-601 series monitor is a microprocessor-based, ground-fault relay for ungrounded dc systems ranging from industrial 24 V dc control circuits to 1000 V dc solar and transportation systems. It provides sensitive ground-fault protection without the problems associated with nuisance tripping. Ground-fault current is sensed using an SE-GRM series ground-reference module—a resistor network that limits ground-fault current to 25 mA. Its output relay can operate in the fail-safe or non-fail-safe mode for undervoltage or shunt-trip applications. The SE-601 relay can be DIN-rail, surface, or panel mounted.

Features

  • Adjustable pickup (1–20 mA)
  • Adjustable time delay (50–2.5 ms)
  • Output contacts
  • Analog outputs (0–5 V)
  • Non-volatile trip memory
  • Selectable contact operating mode
  • Microprocessor-based
