The B325H is a reliable Siemens 3-Pole 25A 240V bolt-on circuit breaker, designed for maximum protection and performance. With a breaking capacity of 22kA, it ensures reliable operation in demanding environments. Ideal for commercial and residential applications, this breaker guarantees safety and efficiency. Trust Alberta Breaker & Supply for your electrical needs.
Yes — the 'H' suffix on the B325H denotes a higher interrupting (short-circuit) rating of 22kA at 240V, compared to the lower kA rating of the standard B325. If your panel schedule or engineer of record specifies 22kA interrupting capacity, you must use the B325H (or equivalent) to meet that requirement. Substituting a lower-rated breaker would not satisfy Canadian Electrical Code fault-current coordination requirements.
The B325H is a 3-pole breaker rated 240V, making it suitable for both single-phase 240V three-wire loads and three-phase 240V (delta) systems. It is commonly used in commercial panelboards for motor branch circuits, HVAC equipment, and similar three-phase loads. It is not rated for 208Y/120V or 480V systems — confirm your system voltage before specifying.
