## Description

Product Description Siemens space saving, plug in circuit breakers are intended for use in Siemens EQ, Siemens Ultimate, ITE, and Gould load centers and meter combinations that are rated to accept type QT breakers. Check wiring diagram to confirm. To ensure the warranty on a Siemens panel is not voided, the use of Siemens breakers is required. The quadplex breakers provide two double pole breakers in half the space of standard sized breakers. These triplex, 1/2-Inch frame breakers are ideal when new circuits are required in a panel that has no available spaces. Siemens strongly recommends against the use of "used" breakers. The installation of used breakers in a Siemens panel will void the warranty on the panel. Siemens does not sell used breakers and has not approved any 3rd party sellers to do so.

## Questions & Answers

**Q: Did inside two terminal for two hot 120 V wire become one 240 V circuit and outside two terminal for other 240V circuit?**
A: Yes the inside pole trip together and outside poles together https://s3.amazonaws.com/dcc-data-extract/new-delta/asset/Compas/daily/Compas/2020-07-02/Specification%20Sheet/SIE_BR_QT.pdf

**Q: Is this compatible with a GE panel?**
A: We do not test our breakers in our competitors panels you would need to get with GE to see if this is approved for their panel.

**Q: Will this work to replace an eaton bq230230?  Eatons compatibility chart only shows single double not quads listed.**
A: I bought this more than 4 years ago for my previous house. If I recall correctly this was a quad breaker for two 220V (using both black & red wires). A double breaker is for two 110V. The overall size for both is the same.

**Q: Will this breaker fit on a full size bus stab or only on the shorter, half length bus stabs?  Please show an image of the breaker jaws.**
A: Load center stabs that accept Type QT breakers will be full size but with a U-shaped notch in them to accommodate the rejection feature of the breaker. These are typically the bottom-most spaces of a load center designed to accept Type QT breakers. Check the label to make sure the QT is listed.

Work great

### ⭐⭐⭐⭐⭐ As ordered

Works great fits snug like it should.

### ⭐⭐⭐⭐⭐ Save space and still use the same slot for two device instead of one.
*by S***I on January 31, 2026*

This time arrived perfectly alligned. This is the ideal breaker to utilize with less space on the breaker box for two 30 Amp consumption devices instead of using the spots provided for only one with the regular wide breaker.
