Protect your alternator with the Pro Protect A alternator protection switch from STERLING. The switch is activated at the exact moment when there are no more electrical consumers, but the alternator is still producing electricity. The Pro Protect A acts as the smallest consumer and consumes the excess electricity. This is of particular importance if the battery main switch is accidentally disconnected when the engine is running. In this case, the alternator has no further electrical consumers and, in the worst case, it can destroy the diodes and thus the entire alternator.
During normal operation, the protection device does not consume any power.
