Description
Built for commercial and industrial applications, this 20-amp current-limiting breaker utilizes thermal-magnetic trip technology alongside integrated fuses. It fits seamlessly into legacy ITE or Siemens Cordonet panelboards, ensuring exact replacement compatibility. The inclusion of Amp-Trap limiters allows the device to achieve a 100kAIC rating at 277VAC, significantly reducing let-through energy during high-level short circuits.Specifications

Product FAQs
6 answersWhat panelboards are compatible with the CC1B020 circuit breaker?
This legacy C-frame breaker is designed specifically for bolt-on installation in ITE and Siemens Cordonet panelboards.
What applications typically use a 277VAC single-pole breaker like the CC1B020?
A 277VAC single-pole breaker is commonly used in commercial and industrial facilities for 277V lighting circuits and dedicated equipment feeders.
What wire sizes and materials are accepted by the lugs on this breaker?
The terminals accept 14 to 1/0 AWG copper wire or 12 to 1/0 AWG aluminum wire.
What does the current limiting designation mean for the CC1B020?
As a current-limiting breaker, it is engineered to clear high-magnitude faults rapidly, reducing the peak let-through current and thermal energy to protect downstream circuits.
How does the trip unit function on this breaker?
It utilizes a fixed thermal-magnetic trip unit, providing long-time protection for standard overloads and instantaneous protection for short circuits.
Are ITE and Siemens CC1B020 breakers interchangeable?
Yes. Siemens acquired ITE, so breakers marked with either the ITE or Siemens brand under the CC1B020 catalog number are physically and electrically identical.
