Overview

The ABB CR306B103 is a NEMA Size 0, three-phase magnetic starter engineered for reliable motor control in industrial environments. Designed for 3 horsepower (HP) applications at 230–240V AC, this starter delivers a continuous ampere rating of 18A, ensuring compatibility with motors drawing up to 18A full load current. The unit features a NEMA Type 1 enclosure, providing protection against solid foreign objects and dust, making it ideal for indoor installations where environmental exposure is minimal. With three poles for balanced three-phase power distribution, the CR306B103 is optimized for non-reversing motor control applications, including pumps, fans, conveyors, and small machinery in manufacturing, processing, and automation systems. Its compact NEMA Size 0 footprint allows for flexible installation in control panels or motor control centers, reducing space requirements while maintaining robust performance. The starter includes a thermal overload relay for motor protection, preventing damage from sustained overloads. For applications requiring alternative environmental ratings, the CR306B series offers NEMA Type 3R (outdoor), Type 12 (dust-tight), and Type 4/4X (watertight/corrosion-resistant) configurations. Key specifications include: NEMA Size 0, NEMA Type 1 enclosure, 3 poles, 3 HP at 230–240V, 18A continuous rating, and a non-reversing design. The ordering code CR306B103 specifies this exact configuration.
