High Voltage Relays Specifications

Help with High Voltage Relays specifications:

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.
	Dielectric Strength (Isolation Voltage)		The American Standards Association (ASA) defines dielectric strength (isolation voltage) as the maximum potential gradient a material can withstand without rupture.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Maximum Current		This is the maximum continuous current allowable across the relay output terminals under the specified heat dissipation and ambient temperature conditions. Generally, AC current is specified in RMS units. Maximum current is also known as the maximum switching voltage range, or the maximum switching current.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	RF Application Rated		Relays can switch frequencies in the RF range. This may include de-rating from a voltage that can be switched at DC or low frequencies.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Additional Specs

	Pole Specifications
	Your choices are...
	Single Pole (SP)		Single pole (SP) relays have a single, moveable lever with a contact at the end.
	Double Pole (DP)		Double pole (DP) relays consist of two, single-pole contacts that are concurrently actuated by the same mechanical system and operation. Typically, the first line is hot and the second is neutral.
	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.
	Throw Specifications
	Your choices are...
	Single Throw		Single throw (ST) relays have a pair of contacts that are open in one position and closed in the other.
	Double Throw		Double throw (DT) relays have three contacts. In one position, the first is in contact with the second, but not the third. In the other relay position, the connection is reversed.
	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.
	Normally Open (NO)		With normally open (NO) devices, the relay contact pair is open when the coil is not energized.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Normally Closed (NC)		With normally closed (NC) devices, the relay contact pair is closed when the coil is not energized.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Changeover (CO)		Changeover relays typically have one set of Form C contacts and are single-pole, double-throw (SPDT) devices.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Make Time (Operate Time)		Make time (operate time, pick-up time) is the time required from actuation to the full current-carrying state.
	Search Logic:		All matching products will have a value less than or equal to the specified value.
	Break Time (Release Time)		Break time (release time, drop-out time) is the time from deactivation to the open state.
	Search Logic:		All matching products will have a value less than or equal to the specified value.

Coil Ratings

	AC Coil Voltage		This is the AC voltage rating of the relay actuation coil.
	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.
	DC Coil Voltage		This is the DC voltage rating of the relay actuation coil.
	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.
	Coil Nominal AC Power		Coil nominal AC power is measured in volt amperes (VA).
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Coil Nominal DC Power		Coil nominal DC power is measured in watts (W).
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Coil Resistance		The resistance of the actuation coil is measured in ohms (Ω).
	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.

Mounting

	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.
