Class 8501 Type X relays combine a rugged, heavy-duty design with modular construction for greater flexibility. They are ideal for applications where long life, high reliability, and ease of maintenance are important. The Type X family offers a complete line of relays and accessories for most control applications. The 8501X relay consists of a standard 4 pole base to which it is possible to add additional contacts, timer, and latch functionality. Instantaneous and Master contacts are converted from N.O. to N.C. by flipping the contact cartridge within the base. The 8501X relay can either be built from individual part numbers or ordered pre-assembled.

Attachments and Accessories for Square D™ NEMA Style Relays
Type X™ Relays
 |
Description |
Type |
||
|
Mechanical Latch Attachment—Mounts on any 2 through 8-pole relay (except XMO master relay). The Type XL and XDL latch attachments are identical in size and mounting provisions. The Type XLAC latch attachment has a continuous-duty-rated coil which is replaceable. The Type XDLDC latch attachment has an intermittent–rated coil (replaceable) and should be connected through a N.O. contact of the basic relay if the input signal is maintained to the unlatch coil. AC Latch Attachment DC Latch Attachment |
XL [6] XDL[6] |
|||
 |
Pneumatic Timer Attachment—Mounts only on any 0 through 4-pole AC or DC relays (except XMO master relay). It provides 1 N.O. and 1 N.C. convertible timed contacts, which are the same Type XC1 cartridges used on the basic relay. Two timing ranges are available, and conversion from On Delay to Off Delay or vice versa is easy. Off Delay 0.2–60 seconds 5–180 seconds On Delay 0.2–60 seconds 5–180 seconds |
XTD1 XTD2 XTE1 XTE2 |
||
|
Timer Lockout Cover—Fits over the time delay adjustment knob of any Type XT timing attachment. The Lockout Cover is designed to protect the time setting against accidental adjustment. It mounts directly to the timing attachment with two included screws. |
XJ1 |
|||
 |
Adder Decks—Adder decks are used to expand the number of poles on a relay. The basic 4-pole relay can be easily converted to an 8-pole or 12-pole relay by installing one or two adder decks. The Class 8501 Type XB20 comes with 2 convertible contact cartridges and will accept 2 additional convertible contact cartridges. The Class 8501 Type XB40 comes with 4 convertible contact cartridges. The same Type XB adder deck is used for both the middle and upper decks of the AC or DC relay. |
|||
|
With 2 N.O. contact cartridges |
XB20 |
|||
|
With 4 N.O. contact cartridges |
XB40 |
|||
|
Contact Cartridges—The Type X relay offers 4 Types of contact cartridges. All are color–coded for visual identification of each Type. |
||||
|
Standard Cartridge—The standard cartridge, used for most applications, has a black case. |
XC1 |
|||
|
Overlapping Cartridge—Same NEMA Type A600 AC rating as standard cartridge and a NEMA Type P150 DC rating. When it is used in the N.O. mode it will close early and when used in the N.C. mode it will open late. If two or more are used together, the N.O. contacts will close before the N.C. contacts open as the relay picks up. Overlap also occurs during dropout. Overlapping cartridge has a red case. |
XC2 |
|||
|
May be ordered factory installed:
|
Form Y1591 Y1592 Y1593 Y1594 |
|||
|
Master Cartridge—Features the same contact ratings as the Type XC1 standard cartridge except it has a 20 ampere continuous current rating instead of 10 amperes. It can be used in circuits where a master relay is required. Master cartridge has a blue case. Maximum of 6 master cartridges may be used on any 7 and 8-pole AC relays. Do not use any master cartridges on 9-12-pole AC or any DC-operated devices. Note: If master cartridges are added to a standard relay, attachments (latch mechanism, timers, etc.) cannot be used. |
XC4 |
|||
 |
Mounting Track—The mounting track has pre-punched mounting holes to simplify mounting the track on the control panel. The relay mounting screws are factory installed on the track so that the relays can be hung prior to tightening the screws. 9 in. long for 4 relays 18 in. long for 8 relays 27 in. long for 12 relays 36 in. long for 16 relays |
XM4 XM8 XM12 XM16 |
||
 |
Manual Test Tool—Provides a means of manually switching the contacts of a basic relay or timing relay and holding all contacts in their switched state until the tool is removed. This simplifies the checking of control circuits without power on the coil or contacts. |
XA1 |
||
|
Transient Suppressor—Consists of an R-C circuit
designed to suppress coil generated transients to approximately 200
percent of peak voltage. It is particularly useful when switching
the Type X relay near solid state equipment. It is designed for use
on coils up to |
XS1 |
|||
|
NEMA 1 Enclosure—Formed from sheet steel to provide strength and rigidity. Two conduit knockouts are located in both the top and bottom of the enclosure. The enclosure is furnished with self tapping screws for mounting the relay inside the enclosure. Accommodates a single 4 or 8-pole AC or DC relay, 12-pole AC relay, 4-pole AC latching relay, and 4-pole AC timing relay. NOTE: The 4-pole DC latching relay, 4-pole DC timing relay, 8-pole AC and DC latching relays and 12-pole utility auxiliary relay will not fit. |
