B325HH - 25Amp Circuit Breaker

B325HH - 25Amp Circuit Breaker

When you’re working with electrical systems that demand higher fault protection, the Siemens B325HH circuit breaker is built to handle the job. This 25 amp, 3-pole Type HBL breaker is designed for 240V applications and helps protect electrical systems from overloads and short circuits before they turn into larger problems. One of the biggest advantages of the B325HH is its 65kA interrupting rating, making it a strong fit for commercial and industrial systems where available fault current levels are higher than average. The thermal magnetic trip mechanism reacts to both ongoing overload conditions and sudden fault events, helping keep panels, wiring, and connected equipment protected during day-to-day operation. Its bolt-on design provides a secure connection in compatible Siemens panelboards, making it a practical choice for maintenance teams, electricians, and facility upgrades. The compact footprint also helps when panel space is tight and every inch matters. The Siemens B325HH is commonly used in industrial facilities, commercial buildings, machinery panels, and power distribution systems where dependable three-phase protection is essential.
