Eaton C320SNP22 Auxiliary Contact Block

The Eaton C320SNP22 is a side-mounted auxiliary contact block designed for definite purpose starters and contactors. It provides four additional contacts rated at 10 A and 600 V AC. The block adds two normally open and two normally closed circuits to compatible control gear.

Suits panels needing extra control circuits

Electricians expanding motor control logic on Series A25, A27, B25, B27 or C25 devices will find this block fits directly. It is not for applications requiring higher current ratings, different voltage classes or front-mount contact arrangements.

Mounts on the side of compatible definite purpose

The block attaches to the side of supported starters and contactors, leaving the front face accessible for other accessories. It draws operating power from the host device coil circuit, so no separate supply wiring is needed.
