B325H - 25Amp Circuit Breaker

B325H - 25Amp Circuit Breaker

The Siemens B325H circuit breaker is a reliable choice for protecting your three-phase electrical systems where a standard breaker may not offer enough interrupting capacity. Rated at 25 amps for 240V applications, this 3-pole Type BLH breaker is built to help protect your electrical equipment, wiring, and branch circuits from overloads and short circuits in commercial and industrial settings. One of the standout features of the B325H is its 22kA interrupting rating, making it a smart fit for systems with higher available fault current. The thermal magnetic trip mechanism reacts to both ongoing overload conditions and sudden faults, helping reduce the chance of equipment damage and costly downtime. Its bolt-on mounting style provides a secure connection in compatible Siemens panelboards and distribution equipment, which can help you simplify installation and replacement work. The compact design is also useful in electrical panels and control cabinets where every inch of space matters. The Siemens B325H is commonly used in commercial buildings, industrial facilities, OEM equipment, and branch circuit applications where dependable three-phase circuit protection is important.
