ABB S203-C16 Circuit Breaker, 16A, 3-Pole, 277V

The ABB S203-C16 Circuit Breaker is a purpose-built solution for protecting three-phase electrical circuits in industrial environments. With a 16 A rating and 277 V nominal operating voltage, this 3-pole device is designed to safeguard larger motor loads, pumps, conveyors, and factory power centers from overcurrent events, short circuits, and wiring faults—and to do so with dependable, trip-ready performance.

Key advantages you’ll notice in real-world use:

• Three-pole protection—simultaneous disconnection of all three phases provides robust protection for 3-phase equipment and minimizes partial fault conditions that can damage motors or drives.
• Industrial-grade reliability—engineered for the demanding environments of manufacturing floors, warehouses, and processing facilities, where uptime matters.
• Clear part-number integrity—the S203-C16 designation lets you verify compatibility at a glance, reducing replacement guesswork during maintenance or upgrades.
• 277V suitability—paired with common industrial distribution systems that run on 277V, this breaker helps ensure safe, predictable operation for line-side protection.
• Easy compatibility check—to confirm fit for your panel or switchgear, reference the part number S203-C16 against your application requirements and existing ABB components.

Who should consider the ABB S203-C16?

• Maintenance technicians performing equipment repairs or panel upgrades in manufacturing, processing, and packaging facilities.
• Electrical engineers selecting protective devices for new 3-phase installations or retrofits where 277V systems are standard.
• Facilities teams consolidating spare parts to streamline service calls and minimize downtime during outages.
