ABB S202-C16 16A 2-Pole 277 V Circuit Breaker

Meet the ABB S202-C16 16A, 2-Pole, 277 V Circuit Breaker — a purpose-built protection device for commercial electrical systems. Designed to handle 277 VAC power distribution, this breaker delivers reliable overcurrent protection for circuits that run on two hot lines, helping to keep both personnel and equipment safe in busy environments.

• Current rating: 16 A
• Poles: 2 (two-pole configuration)
• Voltage rating: 277 V
• Part number: S202-C16
• Brand: ABB

The 2-pole design protects both conductors in a single, integrated unit, ensuring simultaneous disconnection during a fault. With a 16 amp capacity, it’s well-suited for medium-load lighting circuits, HVAC feeds, and other commercial branches that run on 277 VAC, providing a reliable safeguard against overloads and short circuits.

Why this ABB breaker stands out

• Precise, predictable trip performance calibrated for 277 VAC environments common in offices, retail spaces, schools, and industrial facilities.
• Compact, dependable construction from a globally trusted electrical brand, designed for steady operation in demanding installations.
• Clear part-numbering (S202-C16) simplifies replacement, ordering, and cross-referencing within panel schedules and maintenance logs.

Ideal use cases

• Commercial lighting circuits that run at 277 VAC in office buildings, hotels, and retail locations.
• Small-to-medium branch circuits powering fans, pumps, and other equipment in environments where two hot lines are needed.
• Panel board replacements or upgrades where 2-pole, 16 A protection is required for safety and code-compliant distribution.

Practical tips for deployment

• Verify compatibility with your electrical panel’s bus type and enclosure before installation.
• Match the breaker’s 277 V rating to the specific circuits it will protect, ensuring the load does not exceed 16 A for extended periods.
• Consult your facility’s electrical drawings and maintenance logs to determine if a direct S202-C16 replacement will minimize downtime and inventory needs.
