Shipping information

We offer fast and reliable shipping options to ensure that your order arrives in a timely manner. Our dedicated team works diligently to process and ship your items as quickly as possible.

Here are some key points to note about our shipping policy:

Standard Shipping

  • While we endeavour to dispatch all orders promptly, please be advised that due to the current national fuel shortages in Australia and the resulting pressure on logistics networks, order processing and dispatch may take up to 7 business days. We are not liable for delays caused by third-party freight carriers or fuel-related logistical disruptions. By placing an order, you acknowledge that delivery timeframes may be extended beyond our standard estimates during this period.

Estimated delivery times:

  • WA, NT, and TAS: currently experiencing longer shipping times
  • Holiday periods (e.g. Christmas): deliveries may be delayed due to increased freight volumes

Express Shipping

Blue Sea Systems ML Series 500A 12V MC Auto Charge Relay: Designed to Work with Charging and Isolates

500 Amp magnetic latching (bi-stable) relay automatically combines batteries during charging and isolates batteries when discharging and when starting engine.

Blue Sea Systems BS-7622B Features:

  • Manual control switch provides an added level of safety allowing control with or without power, and offering LOCK OFF capability for servicing
  • Automatically manages the charging of two large battery banks
  • Allows paralleling of battery banks for emergency starting
  • 500 Ampere continuous rating to support high-output alternators
  • Magnetic Latch (ML)—ACR draws very low current (<40mA to monitor terminal voltage) in the “ON” or “OFF” states, and draws moderate current for very short time when changing state
  • Dual sensing—senses charge on both battery banks
  • Start Isolation (SI)—can be configured for temporary isolation of House loads from Engine circuit during engine cranking to protect sensitive electronics
  • Engine Isolation (EI)—can be configured for isolation of two engines while both are running to protect engine electronics and maximize alternator output
  • Senses charging on two battery banks
  • LED output to remotely indicate when batteries are combined, isolated, in voltage lockout, or in Start or Engine isolation
  • 3/8″-16 tin-plated copper studs for maximum conductivity and corrosion resistance
  • 7/8″ (22mm) stud length accepts multiple cable terminals
  • Silver alloy contacts provide high reliability for switching live loads
  • Label recesses for circuit identification

ML-Series Remote Control Contura Switch is not supplied with ACR. PN 2146 available as a separate item.
