Blue Sea BS 3000 "Heavy Duty" 2-position ON/OFF battery master switch for diesel and gasoline engines. The switch is ignition protected and suitable for one battery/battery bank.
MAIN FEATURES
- Ignition protected—safe for installation aboard gasoline-powered boats
- Case design allows surface or panel mounting
TECHNICAL DETAILS
- Switch Positions: 2 - ON/Off
- Battery Combining: No
- Color: Gray
- Alternator Field Disconnect (AFD): No (A disconnect switch protects the diodes in the alternator should the switch accidentally be switched to OFF while the engine is running. If the disconnect switch is not used to protect the alternator, an LED can be wired to the AFD terminals to indicate when the battery switch is in any position but OFF.)
- Maximum Voltage: 32V DC
- Terminal Stud Torque: 24.86 Nm
- Continuous Current: 600 Amps.
- Intermittent Current: 900 Amps (5 Min.)
- Cranking Current 10 Sec: 2750 Amps. The current required by the starter motor before the engine starts. Cranking current varies significantly during the starting cycle. Initially, there is a large current surge required to overcome the engine's inertia and compression. This surge can be two to four times the average cranking current. Cranking current is used for sizing batteries, cables, and battery switches.
- Cranking Current 30 Sec: 1750 Amps. The current required by the starter motor before the engine starts. Cranking current varies significantly during the starting cycle. Initially, there is a large current surge required to overcome the engine's inertia and compression. This surge can be two to four times the average cranking current. Cranking current is used for sizing batteries, cables, and battery switches.
- Cranking Current 1 Min: 1325 Amps. The maximum current for which the switch is rated if the starting phase when starting an engine does not exceed one minute.
