BLUE SEA SYSTEMS 7620B, is an Isolator Relay 12 V, 500 AMP magnetic latching (bi-stable) relay automatically combines batteries during charging and isolates batteries during discharge and when starting the engine ;(excl. 2145 switch).
Features
- Includes ML series remote control Contura Switch PN 2146
- Automatically handles the charging of two large battery banks
- Allows paralleling of battery banks for emergency starting
- 500 Amp continuous rating to support high power generators
- Magnetic latch (ML) —ACR draws very low current (<40mA to monitor terminal voltage) in "ON" or "OFF" state and draws moderate current for a very short time when state changes
- Dual sensing - sensing loads on both battery banks
- Initial Isolation (SI) - can be configured for temporary isolation of house loads from the motor circuit during engine cranking to protect sensitive electronics
- Motor Isolation (EI) - can be configured for isolation of two engines while both running to protect engine electronics and maximize alternator output
- Sensing charge on two battery banks
- LED output to remotely connect when batteries are combined, isolated, in voltage lock or starting - or motor insulation
- 3/8 "-16 tin-plated copper pins for maximum conductivity and corrosion resistance
- 7/8 "(22 mm) pin length accepts multiple cable connections
- Connectors in silver alloy provides high reliability for switching power
- Label recesses for circuit identification
