Blue Sea BS 9001e 4 position battery master switch for diesel and gasoline engines. The switch is ignition protected and suitable for two batteries / battery banks.
KEY FEATURES
- Switches isolated battery banks to all loads or combines battery banks with all loads
- Ignition protected for installation aboard a gasoline powered boat
- Case design allows surface or panel mounting
TECHNICAL DETAILS
- Switch positions: 4 - On/Off/to all loads/with all loads
- Battery combining: Yes
- Color: red
- Alternator field disconnect: No (The disconnect switch protects the diodes in the alternator when the switch is turned to OFF while the engine is running. If the disconnect switch is not used to protect the alternator, an LED can be connected to the AFD terminals to indicate when the battery switch is in any position but OFF.)
- Maximum voltage: 32V DC
- Terminal stud torque: 15.82 Nm
- Continuous current: 350 Amps.
- Peak current: 600 Amps
- Cranking current 30 sec: 1200 Amps. The current required by the starter motor before the engine starts. Cranking current varies significantly during the start 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.
