B325 - 25Amp Circuit Breaker

B325 - 25Amp Circuit Breaker

The Siemens B325 circuit breaker is a practical choice for protecting your three-phase electrical systems in commercial and industrial applications. Rated at 25 amps and designed for 240V systems, this 3-pole Type BL breaker helps protect your wiring and connected equipment from overloads and short circuits during everyday operation. Its thermal magnetic trip mechanism responds to both overload conditions and sudden faults, helping you reduce the risk of damage to electrical equipment. The bolt-on mounting style provides a secure fit in compatible Siemens panelboards, making it a reliable option for replacements, upgrades, or new installations. With a 10kA interrupting rating, the B325 works well in a wide range of electrical distribution applications. The compact design also helps save space inside electrical panels and control equipment where room may already be limited. The Siemens B325 is commonly used in commercial buildings, industrial facilities, branch circuit applications, and OEM equipment where dependable three-phase circuit protection is needed.
