General Specifications


	Mounting
	Your choices are...
	Wall / Panel / Backboard Mount		Surge suppressors have bolting or mounting holes so that they can be attached to a wall or backboard.
	DIN Rail		Surge suppressors mount on a DIN rail.
	Hard-Wired / Device Mount		Surge suppressors mount on or within the device that is to be protected from surges.
	In-Line / Integrally Attached		Surge suppressors are threaded, or are designed for integral attachment to conduits, cabling, etc.
	Plug-in Module		Surge suppressors are modules that plug into an existing system or surge suppression device.
	PCB Mount		Surge suppressors are wired or soldered onto printed circuit boards (PCBs).
	Rack Mount Type		Surge suppressors are rack-mounted.
	Other		Other unlisted mounting types.
	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.

	Technology
	Your choices are...
	MOV		Metal oxide varistors (MOV) have high-energy capabilities, good reliability, and consistent performance. They also have a non-linear clamping curve and fatigue rapidly at higher amperage levels.
	Silicon Avalanche Diode		Silicon avalanche diodes have high clamping voltages, but a limited power-handling capacity that is destroyed easily by the power levels encountered in typical power-line surges. Silicon avalanche diodes are used most often in data-line protectors and on circuit boards as static protectors.
	Silicon Thyristor Diode		Silicon thyristor diodes are used mainly to protect telecom systems.
	Gas Tube		Gas tubes have higher energy capabilities than either MOVs or diodes. They typically consist of two electrodes held at a close distance so that high voltages between the electrodes simply arc through the air to effectively clamp the voltage. Gas tubes are very slow, but can handle very large surges.
	Hybrid		Hybrids attempt to incorporate all the major advantages of many of the individual components, while collectively overcoming their individual faults.
	Other		Other, less commonly used technologies include spark gaps, selenium, and Zener diodes.
	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.

Performance


	Maximum Surge Current		Maximum surge current is the maximum current allowed for a single impulse waveform with a continuous voltage applied. This value indicates the protection capacity of a particular surge suppressor design, and is used in specifying a product for a given application. A higher-level surge current capacity is required for a high-exposure application where there are very large transients present from lightning.
	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.

	AC Energy Absorption		AC energy absorption measures a surge suppressor's ability to absorb heat energy created by transient surges. Note that the Joule rating is not a part of IEEE or UL standards.
	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 AC Power		The maximum AC power that the device can handle.
	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.

	Operating Temperature		The full required range of operating temperature.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.

Standards and Features


	Standards
	Your choices are...
	UL 1449 Third Edition		UL 1449 Third Edition is a set of safety standards for surge protective devices (SPDs). The formal title of these standards is "ANSI/UL 1449 & UL Standards for Safety for Surge Protection Devices, UL 1449."
	UL 1449 Second Edition		UL 1449 Second Edition standards apply to devices that are designed to limit repeated transient voltage surges.
	UL 497A Rating		UL 497A is a specification for telephone surge suppressors. These requirements cover secondary protectors for use in single or multiple pair-type communications circuits, not cellular phones.
	UL 497B Rating		UL 497B rating is a specification that covers telecommunication and fire alarm circuits. It protect circuits from surges generated by lightning, inductive switching, electrostatic discharges, and others.
	UL 1459 Rating		UL 1459 covers telecommunications products such as telephone answering devices, residential telephone instruments, telephone dialers, cordless phones, key systems, and private branch exchange (PBX) equipment. These devices are designed to be electrically-connected to a telecommunications network with an operating voltage to ground that does not exceed 200 V peak, 300 V peak-to-peak, and 150 V rms.
