        SKU: THQB32070
        ABB THQB32070 is a 70A, 3-pole bolt-on Q-Line circuit breaker for 120/240V AC systems with thermal-magnetic overcurrent protection and 10 kA interrupting capacity. Commonly used in commercial panels and load centres where a bolt-on branch breaker is required; conductor range and panel compatibility should be confirmed before ordering.

        What this product is for

        The ABB THQB32070 is a Q-Line miniature circuit breaker used to provide branch-circuit overcurrent protection in compatible bolt-on panelboards, load centres, and lighting panels. It is a 3-pole, 70A breaker rated for 120/240V AC systems and uses a thermal-magnetic trip mechanism for overload and short-circuit protection.

        Use for

        • Commercial and light industrial distribution panels that accept ABB / GE Q-Line bolt-on breakers
        • 3-phase branch circuits requiring a 3-pole 70A breaker
        • Applications where 10 kAIC at 120/240V AC meets the available fault current requirement
        • Installations needing a bolt-on mounting style rather than plug-in

        Avoid for

        • Panels not listed for THQB series breakers
        • Applications requiring a higher interrupting rating than 10 kAIC
        • Circuits needing GFCI, AFCI, or other special trip functions not provided by this standard breaker
        • 277/480V systems

        Best for

        Best for electricians replacing or specifying a standard ABB / legacy GE Q-Line bolt-on breaker in existing commercial distribution equipment. It suits jobs where secure bolt-on mounting, 3-pole protection, and straightforward replacement within a listed panel are the main buying factors.

        Installed in

        Typically installed in compatible indoor panelboards, lighting panels, and load centres. As a rule of thumb, a 70A breaker is selected for circuits where conductor sizing, equipment ratings, and calculated load all support that ampacity. Actual application depends on conductor material, termination temperature rating, equipment nameplate, and local electrical code.

        Why this product exists

        This breaker provides a bolt-on branch protection option within the ABB / GE Q-Line platform. Compared with plug-in styles, bolt-on breakers are commonly chosen where panel design or specification calls for a more secure mechanical connection to the bus.

        Compared with similar products

        Compared with a THQL plug-in breaker, the THQB version is the bolt-on equivalent for compatible equipment. This model is a 3-pole 70A unit in the Q-Line family, making it suitable for multi-pole branch circuits where a standard thermal-magnetic breaker is required. Always match the breaker series to the panel listing rather than choosing by amperage alone.
