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.
