Product Details

The Egis Mobile Electric 901643 is a heavy-duty 12V automotive relay rated for 75 amps continuous operation with 150 amp intermittent capacity. Designed for demanding automotive, marine, and powersports electrical systems, this relay features dual-diode circuit protection to prevent flyback voltage from damaging sensitive control circuits.

Key Features:

  • Bi-furcated contacts reduce contact bounce and improve long-term reliability by conducting electrical switching more efficiently, minimizing heat buildup and contact wear
  • Dual diode protection prevents flyback voltage from affecting control signal circuitry, making it ideal for sensitive electronic systems
  • High intermittent rating of 150 amps for up to 3 seconds handles temporary high-amperage startup loads for motors, winches, and other high-draw equipment
  • Extreme temperature tolerance from -50°C to 125°C (-58°F to 257°F) allows installation in engine bays and other high-heat, low-ventilation environments
  • IP54 ingress protection provides dust and water splash resistance for reliable outdoor and under-hood use
  • Reinforced mounting tabs with strengthening gussets ensure secure installation even under vibration, heat, and wire tension
  • Offset terminals with integrated divider design prevent accidental contact shorts between input and output connections

Technical Specifications:

  • Voltage: 12V DC (operating range 8.8-16V DC)
  • Continuous current: 75 amps @ 23°C
  • Intermittent current: 150 amps @ 3 seconds
  • Electrical endurance: 100,000 switching cycles
  • Initial contact resistance: 50 mOhm @ 6V DC
  • Operating temperature: -50°C to 125°C
  • Control connections: Shielded dual 6.3mm x 0.8mm flat blade terminals
  • Power connections: Zinc-plated M5 terminal screws with captive nuts
  • Mounting: Dual elongated holes (6mm x 8.7mm) accept ¼-20" or M6x1.25 bolts or up to #14 screws

Construction and Quality:

  • Automotive-grade design meets or exceeds IEC 60068-2-27 (vibration), IEC 60068-2-6 (shock), IEC 60068-2-2 (temperature), and IP54 (ingress protection) standards
  • High-quality materials provide superior electrical switching performance and extended service life
  • Compact mounting footprint fits confined installation spaces
  • Zinc-plated M5 terminal screws with held-in-place nuts allow easy wire termination and maintain secure connections
  • Elongated mounting holes allow for centering adjustment during installation

This relay is an excellent choice for auxiliary lighting circuits, winch installations, high-output alternator charging systems, fuel pump circuits, and other high-current automotive applications requiring reliable switching and circuit protection.
