Product Details

The Blue Sea Systems 7700100 ML Solenoid is a heavy-duty 12V magnetic latching switch designed for high-amperage marine and vehicle electrical systems. This 500-amp continuous rated solenoid provides reliable switching under load, either manually or from remote locations, making it ideal for battery management, windlass control, and high-current DC applications.

Key Features:

  • Manual Override Knob: Allows control with or without power and provides LOCKED OFF capability for safe servicing
  • Bi-Stable Magnetic Latching: Maintains state without continuous power draw (0mA operating current)
  • High-Current Capacity: 500A continuous, 700A intermittent (5 min), 1450A cranking (30 seconds)
  • Heavy-Duty Terminals: 3/8"-16 tin-plated copper studs with 7/8" length accept multiple cable terminals up to 2x 4/0 AWG
  • Deutsch DTM Connector: Professional-grade control circuit connection for reliable remote operation
  • LED Output: Provides remote indication of switch state (requires optional LED)
  • Silver Alloy Contacts: Capable of switching 300A live loads at 12VDC
  • Corrosion Resistant: Tin-plated components designed for harsh marine environments
  • Label Recesses: Integrated circuit identification areas for organized installations

Technical Specifications:

  • Nominal Voltage: 12VDC
  • Continuous Rating: 500A
  • Intermittent Rating: 700A (5 minutes)
  • Cranking Rating: 1450A DC (30 seconds)
  • Control Circuit: Deutsch DTM connector
  • Terminal Stud Size: 3/8"-16 (M10)
  • Terminal Stud Length: 0.875" (22.23mm)
  • Terminal Stud Torque: 140 in-lb (15.82 Nm)
  • Mounting: #10 fasteners
  • Mechanical Endurance: 100,000 cycles
  • Weight: 1.75 lbs (0.79 kg)

This solenoid is engineered for professional marine and heavy-duty vehicle applications where reliable, high-current switching is critical. The magnetic latching design eliminates parasitic power draw, while the manual override ensures you maintain control even during electrical system failures.

WARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (DEHP) which is known to the State of California to cause cancer, birth defects or other reproductive harm. For more information go to P65Warnings.ca.gov.
