High Voltage Relays Specifications

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 ().
	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.

General Specifications


	Isolation Method
	Your choices are...
	Air Insulated		Air is used as the dielectric.
	Gas Filled		Devices use a gas mixture as the dielectric.
	Reed Relay		Reed relays can switch devices such as solenoids, contactors and starter motors.
	Vacuum		Devices use a vacuum as the dielectric.
	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.

	Features
	Your choices are...
	Sealed Relay		Relays are sealed to prevent the ingress of contaminants, water, etc.
	Latching Relay		Relays are used for latching applications (e.g., latching limit controllers).
	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.
