Siemens 50 Amp Double Pole Type QP Circuit Breaker (Q250)

Model number
Q250

The Siemens Q250 is a 50-amp double-pole Type QP breaker intended for 240V circuits powering large ranges, spa equipment, welders, or higher-output EV chargers. It uses the standard Siemens QP plug-in layout for installation in listed Siemens and Murray residential load centers, occupying two spaces and disconnecting both hot legs together. A thermal-magnetic trip mechanism provides dependable overload and short-circuit protection for demanding household branch circuits. The breaker is rated 10 kAIC for typical residential fault conditions and includes a Siemens Lifetime Limited warranty.

§ FAQ

What is a 50-amp double-pole breaker typically used for?

A 50-amp double-pole breaker is commonly used for 240V hot tubs, larger kitchen ranges, welders, and some EV charging circuits. Those loads need both hot legs disconnected together and conductors sized for a 50-amp branch. The appliance instructions should always be checked before replacing the breaker.

How does the Q250 connect in the panel?

The Q250 is a Type QP plug-in breaker that snaps into two adjacent positions in a compatible Siemens or Murray load center. It contacts both panel phases and provides a linked handle so the entire 240V circuit turns off together. That is the correct arrangement for most residential two-wire 240V loads.

What is the difference between a double-pole 50A breaker and two 50A single-pole breakers?

The double-pole breaker is one listed assembly with common-trip operation across both poles. Two separate single-pole breakers would not guarantee that both hot legs disconnect at the same time and are not a proper replacement for a 240V branch circuit. For homeowner panel work, that distinction is important for both safety and code compliance.

Is the Siemens Q250 compatible with Murray panels too?

Yes, the Q250 is listed for Murray load centers along with Siemens ES, EQ, PL, E, P, W, HW, HPW, G, HG, SGF, SN, XG, and OG series residential panels. You should still verify the panel label before installing any replacement breaker. If the panel requires Type QP, the Q250 is the matching style.
