TECHNICAL DETAILS
- Switch Positions: 3 - On/Off/Battery Combination
- Battery Combine: yes
- Color: red
- Alternator Field Disconnect (AFD): No (Disconnect switch protects the diodes in the alternator if the switch is switched 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 other than OFF.)
- Maximum Voltage: 32V DC
- Terminal Stud Torque: 15.82 Nm
- Continuous Rating: 350 Amps.
- Intermittent Rating: 525 Amps (5 min.)
- Cranking Rating 30 sec.: 700 Amps per circuit. The current required by the starter motor before starting the engine. Cranking current varies significantly during the start cycle. Initially there is a large surge of current required to overcome the inertia and compression of the engine. This surge can be two to four times the average cranking current. Cranking current is used for sizing batteries, cables, and battery switches.
