AC Miniature Circuit Breaker 2 Pole 40A, 120/240V Thermal Magnetic Trip, DIN Rail Mount (6A To 63A Options)

Looking for a solid circuit breaker for your electrical panel or distribution box?

This AC Miniature Circuit Breaker is a 2-pole unit that's super handy for protecting your circuits.

It's a thermal-magnetic type, which basically means it trips if there's an overload or a short circuit – keeping your wiring and equipment safe from damage.

It's rated for 120/240V AC systems, perfect for standard residential or light commercial setups.

This specific one is the 40-amp model, but hey, they come in a bunch of other ratings too – 6A, 10A, 16A, 20A, 25A, 32A, 50A, and 63A – so you can pick the exact one your project needs.

Installation is a breeze because it mounts on a standard 35mm DIN rail (and they even include a small piece of rail and some sleeves in the pack!).

It's got a breaking capacity of 6kA, which is pretty decent for most applications.

It's made with metal and copper components, so it feels sturdy and should last.

The rated impulse voltage (Uimp) is 4kV.

One less thing to worry about – it also works as a reliable isolation switch when you need to cut power to a circuit for maintenance.

Super common in distribution boxes, control panels, and any 50/60Hz AC power system where you need reliable, compact protection.

Honestly, it's just a straightforward, no-nonsense component that does its job well.

Whether you're an electrician stocking up or a DIYer tackling a panel upgrade, having a few of these on hand is always a smart move.

They're the kind of part you install and then forget about because they just work.
