ABB S202-K20 20A 2-Pole 480 V Circuit Breaker

Introducing the ABB S202-K20 20A 2-Pole 480 V Circuit Breaker—a robust protection device built for demanding industrial and commercial panels. With a 20-amp rating and a two-pole design, this breaker interrupts both conductors in the event of an overload or fault, delivering reliable protection for 480 V circuits and safer, faster maintenance.

Key specifications

• Current rating: 20 A
• Poles: 2
• Voltage rating: 480 V
• Part number: S202-K20

Why it matters for your 480 V system

In real-world electrical distributions, a 2-pole breaker like the S202-K20 provides complete circuit isolation by disconnecting both hot lines simultaneously. This reduces the risk of arc exposure during maintenance and improves overall safety. The 20 A rating is well-suited for protecting feeders and branch circuits that power motors, pumps, conveyors, or other equipment in industrial settings, helping prevent damage from overloads and short circuits.

Ideal applications

• Industrial panels and distribution boards that operate at 480 V
• Motor control circuits and feeders requiring reliable overload protection
• New installations or replacements where a precise 20 A, 2-pole, 480 V device is required

Installation and maintenance tips

• Ensure your panel or enclosure supports 2-pole devices rated for 480 V and that the S202-K20 matches the intended circuit rating
• Label the circuit clearly after installation and follow local electrical codes for safe operation
• When replacing an existing breaker, use the exact part number (S202-K20) to maintain system compatibility

Why choose ABB S202-K20

ABB brings decades of engineering expertise to this circuit breaker, combining consistent trip performance with durable construction designed for harsh industrial environments. By selecting the S202-K20, you’re choosing a proven solution from a trusted brand, built to protect critical 480 V circuits and support reliable facility operation over time.
