| Phase | |||
| Your choices are... | |||
| Single-Phase | Devices distribute a single AC voltage. | ||
| Three-Phase | Devices deliver three AC voltages that are 120° out of phase with each other. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Maximum Voltage | This is the maximum voltage that devices can handle safely. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Maximum Current | This is the maximum current that devices can handle safely. | ||

| Main Device | |||
| Your choices are... | |||
| Breakers | Breakers are mechanical switching devices that break currents under specified abnormal circuit conditions. This category includes resettable fuses. | ||
| Fusible | Fuses protect electrical devices and components from overcurrents and short circuits that occur in improperly operating circuits. Fuses contain a metal element that melts when current exceeds specific amperage. | ||

|
|
| ||
| Trip Unit (Breakers Only) | |||
| Your choices are... | |||
| Thermal-Magnetic | To break the circuit, thermal-magnetic breakers use either the current's heating effect or the magnetism created when the current passes through a small coil. | ||
| Electronic | Electronic trip units provide adjustable trip characteristics such as configurable trip thresholds and delays. Some models are microprocessor-controlled. | ||
| Other | Other unlisted trip units. | ||

Switch Control
Back to Top
|
|
| ||
| Switch Control | |||
| Your choices are... | |||
| Manual | Switches are regulated and controlled manually. | ||
| SCADA | Supervisory control and data acquisition (SCADA) switches are used to control distributed systems from a master location. | ||
| Automatic Transfer Control | Switches are used with automatic standby generators that use single-phase or three-phase power and standard voltages during fail over. | ||
| Other | Other unlisted switch control methods. | ||
