Ground Fault Relays Specifications

Help with Ground Fault Relays specifications:

General Specifications

	Mounting
	Your choices are...
	Bracket (Flange) Mount		The relay is equipped with a flange. Typically, this flange is installed by bolting the unit to a matching flange that is welded to a corresponding wall.
	DIN Rail		The relay is equipped with a fastener that can attach to a DIN rail.
	Panel		The relay can be mounted in or on a panel.
	PC Board		The relay can be mounted on a printed circuit board (PCB).
	Socket or Plug-in Style		The relay can be mounted in a socket or on a printed circuit board (PCB).
	Other		Other unlisted mounting 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.

Power Supply

	Power Supply
	Your choices are...
	AC Power Supply		The module requires an AC power supply.
	DC Power Supply		The module requires a DC power supply.
	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.
	Supply Voltage Range		The supply voltage range is the relay supply voltage.
	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.

Sensing / Measurement Range

	Voltage Trigger Range		Voltage-sensing range applies to power (phase), voltage, voltage/frequency, and paralleling (synchronous) sensing relays.
	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.
	Current Trigger Range		Current-sensing range applies to power (phase) and current-sensing relays.
	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.
	Line Voltage Range		Line-voltage range applies to power (phase) sensing relays.
	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.
	Frequency Sensing Range
	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.

Performance

	Maximum AC Switching Voltage		This is the maximum AC switching voltage.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Maximum DC Switching Voltage		This is the maximum DC switching voltage.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

Features

	Features
	Your choices are...
	Automatic Reset		The relay resets automatically after conditions return to normal.
	Sealed Relay		Relays are sealed to prevent the ingress of contaminants, water, etc.
	Programmable Time Delay		The relay has a programmable time-delay feature.
	Synchronous Check (Paralleling)?		Synchronous check or paralleling relays sense the phase-angle displacement and amplitude difference between two voltages. They only permit paralleling when both voltages are equal and in-phase. Generator-to-generator, generator-to-bus (dead bus) and bus-to-bus (double dead-bus) are typical applications.
	Time Delay		Relays provide time delay on make, time delay on break, single shot, recycling, and interval timing functions.
	Visual Indicator		The relay has visual indicator such as a light-emitting diode (LED).
	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.

Environment and Approvals

	Safety Ratings and Approvals
	Your choices are...
	RoHS Compliant		Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated, biphenyl, and polybrominated diphenyl ether. RoHS will become effective on July 1, 2006.
	WEEE Compliant		Waste Electrical and Electronics Equipment (WEEE) is a European Union (EU) directive designed to encourage the reuse, recycling and recovery of electrical and electronic equipment. WEEE is also designed to improve the environmental impact and performance of this equipment. The WEEE directive establishes requirements and criteria for the collection, treatment, recycling and recovery of electrical and electronic equipment. It also makes producers responsible for financing these activities. Retailers and distributors must provide a way for consumers to return used or obsolete equipment without charge.
	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.
	Operating Temperature		This is the full-required range of ambient operating temperature. This represents the surrounding air temperature limits.
	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.
