280-3787 12 Volt Charging Alternator
Cat® 12 Volt Charging Alternator in Cylinder Block
Description
Cat® alternators are designed to supply power to the battery under any operating condition, thereby powering the machine. They have proven to offer first-class ruggedness, durability, and reliability, even at low idle. These alternators come in two types: the brush design uses integral brushes to reduce maintenance, while constant-pressure springs allow the brushes to wear evenly; the other is the brushless design, which has fewer moving parts, tighter air gap tolerances, and excellent sealing for longer service life in harsh environments (dirt, dust, high or low temperatures). Cat® alternators are low in noise, compact, and lightweight, and integrate seamlessly into balanced electrical systems. Every unit is rigorously tested to ensure you get Genuine Cat® reliable performance. Products are available from stock to minimize downtime.
