Physical Specifications


	Style
	Your choices are...
	Ground Mounted		Ground mounted devices permit a variety of bushing orientations for single-sided access or for separate components. This category includes pad mounted and vault mounted devices.
	Pole Mounted		Devices are designed to be mounted on a pole or tower.
	Rack Mounted		Devices are designed to be mounted in an equipment rack.
	Submersible		Submersible devices are designed to be installed underwater.
	Other		Other unlisted styles.
	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.

	Panels
	Your choices are...
	Single-Panel		Devices are single-panel units.
	Multi-Panel		Devices are multi-panel units.
	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.

Electrical Specifications


	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.
	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.

Main Device


	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.
	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.

Trip Unit


	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.
	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.

Switch Control


	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.
	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.
