ENGINEERING DATA SHEET SERIES CSHPB
HALL EFFECT CURRENT SENSOR
FOR BATTERY BUS DIRECT AND RETURN PROTECTION

FEATURES AND CHARACTERISTICS

  • Electronic module in association with a contactor to provide bi-directional protection adapted to current flow direction.
  • Designed for direct mounting on bus bar contactors.
  • Provide an I2t trip law, with accelerated trip time at currents higher than 10 In in the direction battery to bus. In the reversed direction, trip current and law may be defined at different level.
  • No voltage drop in protected line.
  • Trip status provided by an internal latching device.
  • Override input to avoid inadvertent trip during start process.
  • IBIT circuit for high reliability operation.
  • Weight: 110 grams ± 5%.
  • Temperature range: -50°C To +85°C
