Square D BDL36125 - 125 A, 600 V, 2-Pole Circuit Breaker | AmpState

The Square D BDL36125 is a 125A, 600V, 2-pole molded case circuit breaker designed to guard branch circuits in panelboards and load centers. With a focus on dependable overcurrent protection and reliable short-circuit interruption, this unit helps keep residential, commercial, and light industrial electrical systems safer and more efficient.

Compact, space-efficient design

The molded-case chassis is engineered to maximize panel space, allowing you to fit more circuits without expanding the panel footprint. This makes it a practical choice for upgrades, expansions, or new installations where space is at a premium.

Thermal-magnetic trip for stable protection

Equipped with a thermal-magnetic trip unit, the BDL36125 delivers predictable, repeatable protection. The thermal element handles gradual overloads, while the magnetic element provides immediate response during short circuits, reducing nuisance trips and protecting downstream equipment.

Rigid compatibility with OEM panels

Designed to pair with matching Square D OEM load centers and panelboards, this breaker ensures a clean, code-compliant fit and reliable electrical performance in standardSquare D installations.

Ideal applications

With a 125A rating and 2-pole configuration, this breaker is well-suited for branch circuits feeding lighting, receptacle groups, small motors, and general purpose electrical distributions in residential, commercial, and light industrial settings. It’s a solid choice for retrofit panels, service panels, and new builds where robust protection is required without occupying excessive space.
