Stromberg 0KZA1 Auxiliary Contact Block is a compact add-on that provides an extra set of contacts for compatible Stromberg control gear. Also listed as OKZA1 (OKZA-1) in ABB Controls catalogs, the block is rated for 16 A at 600 V, enabling it to handle control-circuit loads in motor starters and control panels. It is designed to extend the auxiliary-contact capability of a main contactor or relay in industrial automation, allowing signaling or interlock functions without altering the main switching path.
