Siemens B2125 125 Amp Double Pole Bolt-On Circuit Breaker

VCAN stocks this 125 Amp Double Pole Bolt-On Circuit Breaker from Siemens for panel work and service upgrades.

It is a double-pole breaker rated 125A. The mounting is bolt-on. It runs on 120V. It is CSA certified.

Breakers are not interchangeable between manufacturers: match the panel's listed breaker type, since a physically similar breaker from another brand voids the listing. 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.
