Fuses: The Dinosaurs of Circuit Protection

From Eaton-ePDU®
 

 
In the interest of saving space and reducing costs, some designers of power distribution/power controllers select fuses as opposed to electro-magnetic circuit breakers as a method of circuit protection. While there is little dispute that fuses can be substituted as over-current protection devices in place of more expensive, and larger
Products & Services
Power transformers convert power-level voltages from one level or phase configuration to another.  They can include features for electrical isolation, power distribution, and control and instrumentation applications. Search by Specification | Learn more about Power Transformers
Power strips are used in applications where multiple AC outlets are needed, often without surge or line noise protection. Search by Specification | Learn more about Power Strips
Toroidal transformers typically consist of copper wire wrapped around a cylindrical core. This design prevents the magnetic flux that occurs within the coil from leaking. Search by Specification | Learn more about Toroidal Transformers
Power distribution units (PDUs) have an electrical input and several outputs, often as electrical outlets, for powering multiple devices.  Search by Specification | Learn more about Power Distribution Units (PDU)
