Feeder Plug-in Circuit Breakers

Choose 1" THQL breakers or ABB's exclusive 1/2" THQP circuit breakers (THQP are available for most load centers). Both are superior products and because the compact THQPs make the most of available panel space, you can install smaller load centers to save money and space in both new installations and service upgrades.
