This Breaker has (2) 15 Amp Single Pole(s) Breakers and (1) 40 Amp Double Pole Breaker in one 2 in. housing. 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. Siemens type QT dual circuit breakers are 1 in. W and consist of (2) 1-pole breakers, in varying combinations of ampere ratings from 15 to 30 Amp. Type QT quad circuit breakers are 2 in. wide and consist of either (1) 2-pole and (2) 1-pole or (2) 2-pole breakers. 2-pole constructions range from 15-50 Amp and are available with internal common trip. All type QT circuit breakers are plug-in style and load terminals are provided with the units. They are rated for 120/240-Volt AC and calibrated for 40C maximum ambient applications. The standard interrupting rating is 10k AIC.
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 triplex breakers provide two single pole and one double pole breakers in half the space. These triplex, 1/2-Inch frame breakers are ideal when new circuits are required in a panel that has no available spaces.
