The GE CR308XT104A is a high-quality Control Power Transformer (CPT) kit designed specifically for GE 300-Line magnetic motor starters. This unit allows you to safely step down high-voltage primary power (240V or 480V) to a standard 120V secondary output, which is used to power the starter's control coils, timers, and pilot lights.
This is a complete field-mounting kit engineered for NEMA Size 1 and Size 2 frames. Its compact design ensures a perfect fit within the starter enclosure, while the rugged construction guarantees reliable performance in demanding industrial automation and motion control applications.
