Thomas & Betts TBBQ220230 Quadplex Circuit Breaker

Description:

The Thomas & Betts TBBQ220230 Quadplex Circuit Breaker is used to provide thermal-magnetic overcurrent and short-circuit protection for multiple 120/240 VAC branch circuits in compatible load centers and panelboards. Commonly installed in residential, commercial, and light industrial electrical systems where one 2-pole 20 Amp circuit and one 2-pole 30 Amp circuit are required while maximizing available panel space. Maintenance electricians, contractors, and facility managers use this quadplex breaker for new installations, panel upgrades, retrofits, and replacement of existing TBBQ Series circuit breakers.

Applications:

The Thomas & Betts TBBQ220230 is a plug-in quadplex thermal-magnetic circuit breaker designed to provide two independent common-handle 2-pole circuits in the space of two standard breaker positions. It features a CTL rejection tab, independent trip operation for each 2-pole circuit, and a 10 kA interrupting capacity for reliable branch circuit protection. The breaker is ideal for HVAC equipment, electric water heaters, air conditioning systems, dryers, multi-wire branch circuits, and other 120/240 VAC applications in compatible Thomas & Betts load centers and panelboards.
