  • Relay is open isolating batteries
  • Batteries are isolated to protect sensitive electronics from voltage sags and spikes

**The maximum current a switch is designed to conduct for an indefinite period.

***The maximum amount of current a switch is designed to carry for a minimum of a designated period of time.

****As a safety feature, some ACRs prevent combining into a severely discharge battery. A dual-sensing ACR will monitor the voltage on both batteries and will not connect if either battery is below the undervoltage lockout level. Use caution when combining into a battery with extremely low voltage, because this might represent a faulty battery or a problem elsewhere in the system.

Protects sensitive electronics by temporary isolation of house loads from engine circuit during engine cranking Designed for 12 or 24 volt systems 12/24 volt auto-ranging voltage input Hermetically sealed contacts/vapor proof Ignition protected—safe for installation aboard gasoline powered boats Supports high-output alternators up to 120 Amperes Dual sensing
