Thomas & Betts TBBQ215215 Quadplex Circuit Breaker

Description:

The Thomas & Betts TBBQ215215 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. Commonly installed in residential, commercial, and light industrial electrical distribution panels where two independent 2-pole 15 Amp circuits are required while conserving 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 TBBQ215215 is a quadplex plug-in thermal-magnetic circuit breaker designed to provide two independent 2-pole 15 Amp circuits within the space of two standard breaker positions. It features independent trip operation, a rejection tab for CTL compliance, and a 10 kA interrupting capacity. The breaker is ideal for HVAC equipment, multi-wire branch circuits, water heaters, small motors, and other 120/240 VAC applications in compatible Thomas & Betts load centers.
