Eaton Cutler-Hammer E22B2 Normally Open Contact Block

The Eaton Cutler-Hammer E22B2 SER.A1 normally open contact block is a 10 A, 600 V accessory that provides a single normally open contact. Identified by the part number E22B2, this block is designed for use with Eaton’s SER.A1 family to add a second contact point to a control circuit. It specifies an N.O. configuration, meaning the contact is open when not energized and closes when the associated device is activated, enabling straightforward control signaling within electrical panels and enclosures. With a 10 A rating at up to 600 V, it supports common, low-to-mid-power switching tasks in industrial control systems where a dedicated normally open path is required. The E22B2 belongs to Eaton's Cutler-Hammer line and the SER.A1 family, helping ensure compatibility with other components in the same series.
