Overview
The Cutler-Hammer C10BN3 is a NEMA Size 0 three-pole non-reversing magnetic contactor designed for general-purpose industrial motor control and switching applications. Part of the Citation series (Series A1), this contactor is engineered for reliable AC power switching and load management in motor starter configurations. The non-reversing design ensures safe, unidirectional motor control, making it suitable for applications where motor reversal is not required.
