The Siemens B330 is a 30-amp, 3-pole, 240V BL series bolt-on circuit breaker designed for use in panelboards, switchboards, and load centers. The BL series features thermal-magnetic trip technology with a 10kAIC interrupting rating at 240V. The B330 is HACR-rated for HVAC and refrigeration loads and is commonly used for 3-phase branch circuit protection in light commercial and industrial applications. It is compatible with Siemens NEMA-type panelboards and is a direct replacement for legacy ITE BL units.
