Relay- R103

Features

  • 80A switching capability
  • Very small contact resistance, hence negligible temp rise inside relay.
  • Pulse driving, single or double coil
  • Low power consumption- 1W / single coil, 2W / double coil
  • Contact form 1-B
  • Custom assemblies available with braided copper wire and / or copper straps, welded to brass terminals.
