The Eaton BA33A Type B Block Overload Relay Starter is a three-pole, block-style overload protection device designed for use in motor starters. As a Type B overload relay, the BA33A provides protective coordination for starter circuits in a compact block package. This model is identified by the BA33A part number and is intended for installation in starter assemblies that require Type B overload protection across all three poles. The block design simplifies mounting and wiring in control panels, helping maintain clear separation of supply and control circuitry in industrial motor applications.
