Description

Siemens offers a wide array of thermal-magnetic circuit breakers that are the key element for overload and short-circuit protection of your home's electrical system. To provide additional protection Siemens offers circuit breakers to protect against severe electrical shock or electrocution, mitigate the risk of electrical fires and protect against damaging surges and Voltage spikes. Circuit breakers are intended for switching and protection of your home's wiring from high temperatures caused by excess current higher than the rating of the wire. While thermal-magnetic circuit breakers are the key element for overload and short-circuit protection of your electrical system, there are potentially dangerous conditions that do not involve over current. To ensure the warranty on a Siemens panel is not voided, the use of Siemens breakers is required. 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. From the Manufacturer Siemens plug in circuit breakers are intended for use in Siemens EQ, Siemens Ultimate, ITE, and Gould load centers or meter combinations. The double pole Siemens breakers may be used in 1 or 3-phase load centers and are 240V rated. To ensure the warranty on a Siemens panel is not voided, the use of Siemens breakers is required.

  • Dependable and Easy to Install Circuit Breaker
Size: 40 Amp Style: 1 Pack Pattern Name: Breaker
The Siemens Q240 40-Amp Double Pole Circuit Breaker has proven to be a reliable component in my recent electrical upgrades. I recently used it to replace an old breaker in my home’s main panel, and the process was surprisingly smooth. One thing that stood out was the ease of installation. It snapped into place securely, and the connections were straightforward, making the whole process quick and hassle-free. The build quality is impressive too; it feels robust and well-made, which adds a level of confidence in its long-term reliability. What I appreciate most is its performance. It has been running flawlessly since installation, handling the load without any issues. The peace of mind that comes with knowing your electrical system is safe is invaluable. If I had to point out a minor downside, it would be that the black color can make it a bit tricky to see in a dimly lit panel box. But that's a small trade-off for a product that works this well. In short, the Siemens Q240 has been a fantastic upgrade, and I’d highly recommend it to any DIYer tackling electrical projects. ... show more
