Siemens B320 20 Amp 3 Pole Bolt-On Circuit Breaker

Siemens builds this 20 Amp 3 Pole Bolt-On Circuit Breaker for residential and light-commercial distribution.

It is a three-pole breaker rated 20A. The mounting is bolt-on. It runs on 120V. It is CSA certified.

Bring the panel's model number when ordering a replacement; the catalogue number on the old breaker is the fastest way to get the right one first time. Confirm the interrupting rating alongside the trip rating — the amperage on the handle is only half of what makes a breaker correct for a panel.

Send this through as a quote request and we will confirm pricing and availability before anything is committed. Quote by SKU B320. More options in Breakers.
