The Schneider Electric LRD line of Class 10 bimetallic overload relies on up to 140 A. They are bimetallic ambient compensated and are available with or without single-phase sensitivity for phase unbalance and phase loss protection. New solid state overload relays are available for 90 to 150 A applications. Both bimetallic and solid-state overload relays include the following features:
• Isolated N.C. trip contact and N.O. alarm contacts.
• Manual or Automatic reset function (bi-metallic versions only).
