Information About B2125
The Siemens B2125 is a 125 Amp, 240 Volt, 2 Pole circuit breaker designed for panel board mounting. It belongs to the BL Series of molded case Bolt-On Circuit Breakers, featuring a non-interchangeable trip mechanism. Manufactured by Siemens, it is identified by Cat. No. B2125 and is characterized by its bolt-on connection type and single-phase operation.
Key specifications include an interrupting rating of 10000 Ampere, ensuring robust performance under fault conditions. The breaker's physical dimensions are 3.5 inches in height, 2 inches in width, and 3 inches in length, suitable for various panel board configurations. It is certified by CSA (Canadian Standards Association) and UL (Underwriters Laboratories) as an authentic Siemens product, meeting stringent safety and reliability standards.
The B2125 is designed to protect electrical circuits against overcurrent situations. Its thermal magnetic trip type combines thermal protection (for sustained overloads) and magnetic protection (for short-circuit events), ensuring prompt circuit interruption to prevent damage to equipment and wiring. This dual protection mechanism enhances operational safety in residential, commercial, and industrial applications.
