Arrow Hart CRA-231-U Motor Starter

Arrow Hart CRA-231-U Motor Starter is a compact magnetic starter that switches motor loads from a 110–120 VAC control circuit and uses a 60 Hz coil to energize its contacts. The unit is rated to handle up to 45 A on the load side, making it suitable for small-to-mid-size motors in industrial equipment such as conveyors, pumps, and fans where reliable on/off control is essential. This model sits within Arrow Hart’s family of manual motor controllers and disconnect switches, known for rugged construction and straightforward wiring in demanding environments. The CRA-231-U designation identifies this exact coil/load configuration, specifically a 110/120 V, 60 Hz, 45 A motor starter. When selecting replacement or new installations, buyers typically verify these coil voltage and frequency specs against their motor, power source, and protection scheme to ensure proper coordination with fusing and overload protection and to meet applicable electrical codes.
