KISSLING Series 28 / 30 (EC) Bi-Stable Relays

KISSLING Series 30 (EC) Bi-Stable Relays with Control Electronics

This Bi-Stable relay is based on the Series 30 industrial relay and has all of the same quality mechanical and electrical switching characteristics - but also features additional electronic functions for pulse protection of the coil, a low energy switching input for direct connection to an ECU, as well as optional current and voltage sensing on the main contacts


  • Highest quality industrial bi-stable relay
  • IP67 & IP6K9K (steam cleaning) sealing technology
  • Integrated electronics for coil protection & control, direct connection to an ECU, and status output
  • Optional current & voltage sensing direct at the switching point - improves safety levels and reaction times in critical situations.  
  • Wide variety of configuration options for individual needs

Technical Data

  • Main contact current rated for continuous current and 100% duty cycle
  • Rated for minimum 100.000 switching cycles under full load
  • Mechanical life tested for 2 million mechanical cycles
  • 6 G shock & 4 G vibration resistant
  • Rated for -40°C to +85°C environmental operating temperature

Application Areas

  • Power Distribution
  • Remote Battery Disconnect
  • Battery Management
  • HVAC Control
  • Auxiliary Power Systems
  • Battery Charge/Discharge Monitoring

This relay is particularly well suited for battery management and power distribution applications on commercial vehicles, buses, construction & agricultural vehicles, aircraft, ground support equipment and lift trucks. Other important advantages include a status output for direct monitoring of the switching state and optional programmable time delay for both making and breaking contact. The electronic functions directly coupled to the relay not only reduces peripheral circuitry and costs in the vehicle itself, but also improves safety levels in critical switching applications. The series 30 (EC) includes power relays in nominal voltages of 12 & 24 V and nominal continuous amperages of from 200 Amps to 300 Amps. Detailed information regarding the various types is available on request. Custom relays can be developed in accordance to client specifications.
