Blue Sea 7621100 ML ACR Charging Relay 24V 500A w/Deutsch Connector — Product description

7621100 ML ACR Charging Relay 24V 500A with Deutsch Connector

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

Features:

  • 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

Specifications:

  • Control Circuit Connection: Deutsch DTM
  • Nominal Voltage: 24VDC
  • Manual Control: No
  • Engine Isolation: Yes
  • Mounting: #10

  • Intermittent Rating: 700A (5 min)
  • Cranking Rating 30 Seconds: 1450A DC
  • Cable Size to Meet Ratings: 2x (4/0)
  • Live Current Switching: 300A@12VDC
  • Master Control Switch Capability: No
  • Switching Cycles: 100,000
  • Terminal Ring Diameter Clearance: 1.18" (29.97 mm)
  • Terminal Stud Length: 1.50" (38.1 mm)
