Siemens CC2B020 20A 2-Pole 480 V Circuit Breaker

Siemens CC2B020 is a 20A, 2-Pole, 480 V circuit breaker designed for reliable overcurrent protection in commercial and light industrial electrical systems. Part number CC2B020, this breaker interrupts both hot legs in a 480V distribution, helping protect wiring and equipment from overloads and short circuits.

Key specifications

• Current rating: 20 A
• Poles: 2
• Voltage rating: 480 V
• Part number: CC2B020

Why this two-pole, 480V solution stands out

The 2-pole configuration ensures simultaneous disconnection of both live conductors, which is critical for 480V circuits where single-pole protection can leave a shared fault path. By pairing a precise 20A rating with robust construction, the CC2B020 provides consistent protection for branch circuits feeding motors, conveyors, or other 480V equipment in busy facilities. Its Siemens engineering emphasizes dependable mechanical operation and predictable trip behavior, aligning with standard electrical codes and panel requirements.

Ideal use cases

• Protecting 480V distribution lines in commercial buildings, data centers, and light industrial spaces
• Guarding two-pole circuits that feed equipment with 20A demand, such as motors and control hardware
• Replacement breaker in panels designed to accept CC-series Siemens breakers

Installation and compatibility

Confirm that your electrical panel accepts CC-series breakers and that a 2-pole, 480V device is the correct choice for the circuit you’re protecting. Install in accordance with local electrical codes, and replace only with the same amperage rating and pole configuration to maintain system protection integrity.

Practical tips

• Label the breaker clearly in your panel directory to reflect its protected load
• Keep spare CC2B020 on hand for quick replacements to minimize downtime
• Pair with appropriate wiring and enclosure rated for 480V operation
