The B250HH Siemens (HBL) 2P 50A 240V Bolt-On Breaker is designed for reliable performance in demanding applications. With a robust 65kA short circuit interrupting capacity, this circuit breaker provides exceptional protection and efficient operation. Ideal for residential and commercial needs, it ensures safety and reliability in your electrical system.
The "HH" suffix on the B250HH denotes its high interrupting capacity — rated at 65kA short circuit current interrupting (SCCR), compared to the standard 10kA or 22kA ratings found on typical residential breakers. This makes the B250HH suitable for commercial or industrial installations where the available fault current at the panel is significantly higher.
The B250HH is a bolt-on breaker, meaning it mechanically fastens to the bus bar rather than clipping on. Bolt-on and plug-on breakers are NOT interchangeable — your panelboard must specifically accept bolt-on breakers. Check your panel's labelling or door schedule, or contact us with your panel model and we can confirm compatibility.
Availability of the HBL-frame B250HH can be limited depending on production status. Northern Breaker Group specialises in obsolete and hard-to-find Siemens breakers and maintains access to surplus and reconditioned stock.
