Buying Guide

Match breaker type to panel

Confirm your panel requires QP-style breakers and compatible double- or single-pole configurations before purchasing

Pick the correct amp rating

Choose the ampere value (e.g., 15A, 40A, 50A, 60A, 90A, 100A) to match circuit load and downstream device requirements

Prefer magnetic trip characteristic

Magnetic (instant-trip) breakers are optimal for short-circuit protection; verify the breaker is specified as a magnetic or magnetic-only trip if that is required

Buy from known manufacturers

Select breakers from established brands like Siemens to ensure dimensional and electrical compatibility with common panels

Check packaging and quantity options

Consider multi-packs for multiple circuits or spare parts—3-pack options can lower unit cost and simplify panel upgrades
