The B330HH SIEMENS (HBL) 3P30A 240V Bolt On Breaker is engineered for high-performance applications, offering a robust 65kA interrupting capacity. This three-pole circuit breaker ensures reliable protection for electrical systems, making it ideal for residential and commercial use. Experience peace of mind with dependable circuit protection in your installations.
The "HH" suffix denotes a high interrupting capacity rating of 65kA, compared to the standard BL series which is typically rated at 22kA. The B330HH is the right choice when your panel's available fault current exceeds the standard breaker's interrupting rating — common in commercial installations or when connected close to a large transformer.
In most cases, yes — Siemens acquired ITE, and the HBL bolt-on series is the modern successor to legacy ITE bolt-on breakers with the same frame. However, you should verify your panelboard accepts the BL/BA bolt-on style and confirm the bus stab spacing. Contact our team with your existing breaker part number or panel model and we'll verify compatibility before you order.
