Siemens Hi Q220 20A Double Pole Circuit Breaker for Residential Use

Siemens offers a wide range of thermal-magnetic circuit breakers, which play a crucial role in protecting your home's electrical system from both overload and short-circuit conditions. In addition to these, Siemens also provides circuit breakers designed to protect against severe electrical shock, reduce the risk of electrical fires, and safeguard against damaging surges and voltage spikes. The primary function of these circuit breakers is to switch and protect your home's wiring from excessive temperatures caused by an excessive current flowing through them.

While thermal-magnetic circuit breakers are indispensable for protecting against overload and short-circuit scenarios, there are other potentially hazardous conditions that do not involve overcurrent. Using Siemens breakers is necessary to ensure that the warranty on a Siemens panel is not voided. Siemens strongly advises against the use of "used" breakers, as installing used breakers in a Siemens panel will invalidate the panel's warranty. Siemens emphasizes that they do not sell used breakers and have not authorized any third-party sellers to do so.

Siemens plug-in circuit breakers are specifically designed for use with Siemens EQ, Siemens Ultimate, ITE, and Gould load centers, as well as meter combinations. The double-pole Siemens breakers are suitable for use in both 1 and 3-phase load centers, and they are rated for 240V. It's important to use Siemens breakers to avoid voiding the warranty on a Siemens panel. The double-pole, 20 Amp, 240V type QP Circuit Breaker has a 10,000 AIC interrupting rating, providing easy plug-in connections in Siemens enclosures and featuring the time-saving Insta-Wire feature. These breakers are compatible with Siemens PL and ES series load centers and are intended for overload and short-circuit protection of your electrical system. They also accept #14-8 AWG AI wire.
