Product Description

The Motor & Armature Inc 12907 Oval Run Capacitor 7.5 MFD 370V functions as a power storage system that enhances electric motor performance through its ability to store and release electrical energy when needed for maintaining smooth motor operations. The electrical current receives a phase shift from this component that results in a balanced power supply that reduces motor strain and improves performance. The capacitor functions to stabilize voltage fluctuations protecting the system from sudden power drops that can cause damage.
