Section 1

Application The CR387/487 nonreversing starters are designed for more accurate fault protection for motor circuits by utilizing Spectra ™ Mag-Break motor circuit protectors for sizes 0-4 and Type TJC for size 5. Spectra ™ Features —Spectra ™ Mag-Break motor circuit protector —provides protec- tion against faults. Has adjustable trip. —Meets NEC standards —continuous current ratings and adjustable instantaneous trip ranges meet NEC standards on motor full-load and locked rotor currents. —Can eliminate nuisance tripping and provide fault protection — by setting the Mag-Break instantaneous trip point just above transient motor inrush current . —Less than one cycle clearing time —to open and clear a fault . Example: A size 2 combination starter is required to control a 15-hp, 230-Volt , 60-Hertz nonreversing motor with FLA of 42.0. The starter will include a Mag-Break motor circuit protector, 230-240 Volt , 60-Hertz coil, and a three-leg block overload. Order 1—CR387DT03MJ1AAAAA at $1122.00, GO-10G1 , and 3—CR123C460B heaters.
