Blue Sea Systems ML-Series 500 Amp Magnetic Latching Solenoids: High-Voltage, Reliable Switching for Multi-Voltage Systems

Blue Sea Systems ML-Series Solenoids are 500 Amp magnetic latching solenoids, designed for high-performance switching under load without requiring manual control. These solenoids are equipped with 3/8"-16 tin-plated copper studs, ensuring maximum conductivity and corrosion resistance. The silver alloy contacts provide reliable switching for live loads, making them ideal for applications like engine, inverter, and emergency battery combines.

With an LED output for remote switch state indication, these solenoids can be monitored via an optional LED or Remote Control Contura Switch with integrated LED (Del #5456). The magnetic latching design draws no current in the "ON" or "OFF" state, consuming power only when switching the solenoid’s state. Now rated up to 64V DC for contact voltage, these solenoids are perfect for multi-voltage systems such as solar or golf carts, maintaining the standard 12V or 24V DC control voltage while supporting up to 2,000 live-switching cycles at maximum operating voltage, tested to UL 1107 standards.

The ML-Series is designed for heavy-duty applications, providing reliable and efficient switching across a range of voltage systems.


  • Nominal Control Voltage: 12V or 24V
  • Operating Voltage (contacts): 0-64V, or 9-16V or 18-32V depending on part number
  • Solenoid accessories can be found here.
  • Download data sheet for 5465 and 5467 here.
  • 500 Ampere continuous rating for engine, inverter, house loads, and emergency battery combine
  • LED output to remotely indicate switch state - requires optional LED or Remote Control Contura Switch w/LED (includes Contura Switch Del #5456 (BSS 2145))
  • Magnetic latching draws no current in "ON" or "OFF" state, only draws current when changing state of switch
  • Silver alloy contacts provide high reliability for switching live loads
  • 3/8"-16 Tin-plated Copper studs. 0.875" (22.23 mm) stud length accepts multiple cable terminals.
  • One-piece stainless flange nuts ensure safe and secure connections. Label recesses for circuit identification.
  • CE marked, meets ISO 8846 and SAE J1171 external ignition protection requirements IP66 - protected against powerful water jets

Blue Sea Systems ML-Series 500 Amp Magnetic Latching Solenoids: Reliable Switching for High-Voltage and Multi-Voltage Systems

Blue Sea Systems ML-Series 500 Amp Magnetic Latching Solenoids are designed for high-demand applications, providing reliable switching under load without requiring manual control. These solenoids feature 3/8"-16 tin-plated copper studs for maximum conductivity and corrosion resistance, ensuring secure and efficient connections. The silver alloy contacts deliver dependable switching of live loads, making them suitable for critical electrical applications such as engines, inverters, and battery combines.

A standout feature is the LED output, which can remotely indicate the switch state, and is compatible with an optional LED or Remote Control Contura Switch with an integrated LED (Del #5456 included in the retail package). These solenoids are now rated for up to 64V DC on the contact side, making them ideal for multi-voltage systems like solar installations, 36V DC, and 48V DC nominal systems, such as golf carts. Importantly, the control voltage remains at either 12V DC or 24V DC, maintaining compatibility with standard vehicle and industrial systems. This higher voltage capability has been rigorously tested for up to 2,000 live-switching cycles at maximum operating voltage, meeting UL 1107 requirements.

Ideal for use in solar, marine, automotive, and industrial applications, the ML-Series provides high-efficiency switching for complex electrical systems.
