It's not a problem. Several ways to go.

This answer is confined to products authorized by competent, recognized testing laboratories which meet first-world standards. Obviously you can get anything from certain countries on certain sites, but in AC mains power, you shouldn't.

Note that remote reset of a tripped residential-market breaker is forbidden by the standards bodies of most first-world nations.

Shunt-trip breakers

Shunt-trip breakers have 2 extra wires or terminals. You apply power (typically 24 volts) to them and this trips the breaker.

The breaker must be manually reset once tripped.

In European "DIN Rail" breaker lines, the shunt-trip is typically an additional module stacked with the breaker, with an interconnecting rod that taps the common trip mechanism built into breakers with this capability. Consult your supplier.

These are readily available in all major circuit breaker lines (Square D "HomeLine", talk about truth in advertising, does not support them; however Eaton supports HomeLine panels with their "CL" line of breakers.)

Generally, "shunt trip" breakers occupy one additional standard-size breaker space to house the shunt-trip equipment.

"Smart" Shunt-Trip breakers

Some new "smart panels", for instance Leviton's, provides a way to shunt-trip a breaker remotely via the smart controls/app/API/whatever. It's doing the exact same thing: shunt-tripping the breaker.

The breaker must be reset manually.

Remote-Control Breakers

This appears to be an Eaton exclusive in North America.

This breaker provides extra wires: "Common", "On" and "Off". Placing a 24V impulse for a short period (around 1 second) between common and "On" or "Off" causes an internal switch to throw that way. Yes, you have remote turn-ON.

Why is this legal? Because the onboard switch is separate and in addition to the circuit breaker, and with a separate throw handle separate from the breaker. If the breaker itself trips it must be hand-reset. Functionally this is a regular breaker + a GE RR7 style latching relay.

You can accomplish "must be reset by hand" simply by only connecting wires to "Off" and "common" and leaving the "On" terminal connected to nothing. However you have a perfect right to command it "ON" since you are not controlling the breaker.

Eaton makes these available for almost all 1" wide residential breaker lines including legacy lines, and their BAB line of bolt-on breakers. This is via Eaton's "CL" breaker line, which is specifically designed and UL-Classified for competitor panels. Other than that, North American breaker do not interchange.

Smart breakers

This is the emerging world of true "smart breakers" which are networked with some sort of supervisory system in the panel, and provide full on/off control via an app or API. The SPAN panel is the first North American example of this, but I expect it to take off very quickly due to the pressures acting on the power marketplace. Particularly around demand-side management and electric vehicle home charging.

However it is not any larger than a normal breaker.

The "sense" wire indicates either switch handle position or breaker handle position, depending on model.

Yes, there's not a problem there. There are two approaches to this (well 3 actually, well hmm, 4.)
