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.

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. 
   Triple Pole (TP)       Triple pole (TP) relays consist of three single-pole contact systems. 
   Four Pole (4P)       Relays with more than three poles are indicated by the number of single-pole contacts followed by the letter "P". For example, four-pole relays are 4P devices. 
   > 4 Poles       This category includes relays with more than four circuit contacts. 
   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.

Number of Contacts
   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.

Contact Ratings
   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.
   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.
   Maximum AC Switching Power       The maximum AC switching power is measured in volt amperes (VA). 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Maximum DC Switching Power       The maximum DC switching power is measured in watts (W). 
   Search Logic:      All matching products will have a value greater 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 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.
   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.

Performance
   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.

Features
   Features       
   Your choices are...         
   Convertible Contacts       Convertible contacts can be reconfigured from normally open (NC) to normally closed (NC), and vice versa. 
   Current Sensitive       Current sensitive relays indicate when a preset AC or DC current threshold is exceeded.   
   Latching Relay       Relays are used for latching applications (e.g. latching limit controllers). 
   Mercury Wetted Contacts       Mercury is used to wet the contacts and ensure a good connection. 
   Sealed Relay       Relays are sealed to prevent the ingress of contaminants, water, etc.    
   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.
