Description
Built for older electrical systems, the Siemens P2020NC is a Non-CTL tandem breaker that lacks a rejection clip, allowing installation in pre-1968 ITE and Pushmatic load centers. This 20/20A unit maximizes panel capacity by fitting two independent circuits into a single-pole footprint. Utilizing the signature push-button mechanism and a secure bolt-on connection, it ensures stable thermal-magnetic protection. For contemporary replacements, this breaker crosses over to the UBIP2020.Specifications

Product FAQs
7 answersWhat panels accept the Siemens P2020NC breaker?
It is designed specifically for legacy ITE, Bulldog, and Siemens Pushmatic load centers.
What does the NC designation mean on the P2020NC?
The NC stands for Non-CTL (Circuit Total Limiting). This means the breaker does not have a rejection clip, allowing it to be installed in older, pre-1968 Pushmatic panels that lack CTL rejection features.
How is the P2020NC actuated and reset?
Unlike standard toggle breakers, Pushmatic series breakers utilize a unique push-button mechanism. To reset a tripped circuit, press the button firmly.
Does the P2020NC use a plug-in or bolt-on connection?
While tandem breakers are often plug-in, the Pushmatic series utilizes a secure bolt-on mounting style to attach to the panel bus bar.
What is the direct cross-reference for the Siemens P2020NC?
For contemporary replacements, this breaker crosses over to the Connecticut Electric UBIP2020, which is designed to fit the same Pushmatic load centers.
How does a tandem configuration work on the P2020NC?
As a tandem or twin breaker, it maximizes panel space by providing two independent 20-amp circuits within a single-pole footprint.
Is it safe to install a Non-CTL breaker in any panel?
Non-CTL breakers like the P2020NC are intended strictly for replacement use in older panels installed before the 1968 National Electrical Code (NEC) adoption of Circuit Total Limiting rules. Always verify your panel labeling allows for non-rejection tandem breakers.
