Product Description Siemens BL breakers provide easy bolt-on connections in Siemens panelboards. Siemens offers 3 AIC ratings for these breakers: BL at 10K AIC, BLH at 22K AIC, and HBL at 65 K AIC. They are available in 10-125 Amp, with 1, 2 and Triple Poles. All circuit breakers are designed to sense when an over current occurs, measure the amount of over current and lastly, act by tripping quickly enough to prevent damage to itself and associated conductors.
