Description
ABB S283-K10W S283 K10A 480Y/277V 10kA 3-Pole DIN Rail Circuit Breaker K Curve
The ABB S283-K10W is a three-pole miniature circuit breaker (MCB) from ABB's S280 series, designed for DIN rail installation in industrial and commercial electrical distribution panels. It carries a 10-ampere rating with a K-curve trip characteristic, making it suited for loads with high inrush currents such as transformers, solenoids, and motor control circuits. The 10kA interrupting capacity provides protection against short-circuit faults in 480Y/277V three-phase systems.

Applications
The ABB S280 series miniature circuit breakers are used in industrial control panels, machine tool enclosures, commercial distribution boards, and building automation systems requiring DIN rail-compatible branch circuit protection. The K-curve trip characteristic is specifically chosen for circuits where high inrush current is expected at startup — such as transformer primaries, solenoid valves, and motor starters — where a standard B- or C-curve breaker would nuisance-trip. Three-pole configurations are standard in three-phase branch circuits and are commonly found in industrial machinery, HVAC controls, and process equipment panels. The 480Y/277V rating makes this breaker appropriate for North American industrial power distribution systems running on a wye-configured 480V service.
This ABB S283-K10W 3-Pole DIN Rail Miniature Circuit Breaker has been inspected and is in good used condition. The housing is clean with no cracks or significant damage; the toggle handle, trip indicators, and DIN rail clip all appear intact and functional. Minor surface scuffing consistent with normal use is present. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
