Siemens Q330H 30-Amp 3-Pole 240-Volt Circuit Breaker – 22kA Interrupting Rating, Plug-In Type, QP Frame, 1" Per Pole

About This Product

If you're working on a 240-volt circuit that needs a 3-pole breaker, this Siemens Q330H is a solid bet.
It's rated at 30 amps and has a 22kA interrupting capacity – that means it can handle a pretty serious short circuit without welding itself shut.

It's a Type QP plug-in breaker, which is the standard for many Siemens load centers and panels.
Each pole takes up 1 inch of space, so it's a 3-inch wide unit total.

This is a Type QT breaker – which is Siemens' designation for their 3-pole offering in this style.

It snaps right into the panel bus, no tools needed beyond a screwdriver for the wire connections.
The 240-volt rating makes it suitable for heavy appliances, HVAC equipment, or subpanels that need three-phase-ish power (in a split-phase panel).

The build quality is typical Siemens – solid, reliable, and meets all the relevant UL standards.

If you're replacing a bad breaker or adding a new circuit, this is the one you want.
Just make sure your panel accepts this style – most Siemens and some other brands do.

It's a straightforward, no-nonsense breaker that does its job silently in the background.

Safe, reliable, and built to last.
