Eaton XTMCXFD11 – Frequently Asked Questions
1) Which contact arrangements can I get on the Eaton XTMCXF auxiliary block?
Four versions cover the usual logic needs. XTMCXFA22 is 4-pole 2NO-2NC. XTMCXFA40 is 4-pole 4NO with screw terminals. XTMCXFC22 is 4-pole 4NO with spring cage terminals. XTMCXFD11 is a 2-pole, 1NO-1NC/2NO block. Pick 4NO when you just need parallel signalling or seal-in contacts, and a version with NC poles when you need interlocking or fault logic that breaks on pull-in.
2) I need an auxiliary contact for a circuit breaker, not a relay. Is this the right part?
No. The Eaton XTMCXF block is an accessory for XTRM miniature control relays and mounts on the front of the relay, so it will not fit a breaker or a disconnect. For breaker status you want a breaker-specific kit such as the Square D ComPact NSXm auxiliary contact for OF/SD breaker status, or the Square D Type S isolated alarm contact kit. For a rotary disconnect, the ABB OA1G10 1-NO auxiliary contact switch is made for OT/OS disconnects.
3) Can an ABB CR305X auxiliary contact be used in place of the Eaton XTMCXF front-mounted auxiliary contact?
Not interchangeably. The Eaton XTMCXF auxiliary contact is a front-mounting block built to add contacts to Eaton XTRM miniature control relays, so it seats on that relay family's front face. The ABB CR305X series auxiliary contact is an ABB accessory for ABB contactors and relays and mounts to those devices. Both are add-on auxiliary contact blocks, but each is keyed to its own manufacturer's relay body, so pick the block that matches the device already in the panel rather than mixing brands.
4) I need auxiliary status contacts on a disconnect switch, not a control relay. What should I use instead of the Eaton XTMCXF?
Use a disconnect-mounted auxiliary switch. The Eaton XTMCXF auxiliary contact block is made to mount on the front of Eaton XTRM miniature control relays, so it has nothing to attach to on a disconnect. The ABB OA1G10 is a 1-NO auxiliary contact switch intended for ABB OT and OS disconnect switches, which is the right style of part when you are signaling open/closed position of a disconnect rather than expanding relay contacts.
5) What is the difference between the Eaton XTMCXF auxiliary contact and a Square D ComPact NSXm auxiliary contact?
They report different things. The Eaton XTMCXF block adds auxiliary poles to an Eaton XTRM miniature control relay, available in arrangements such as 4-pole 2NO-2NC, 4-pole 4NO, and 2-pole configurations, rated 10A conventional thermal current. The Square D LV426950 is a ComPact NSXm auxiliary contact providing OF/SD circuit breaker status, meaning it signals breaker on/off and trip state inside a molded case breaker. If your point is breaker status in a distribution panel, the NSXm contact is the matching part; if it is relay contact expansion in a control panel, the Eaton block is.
6) Screw or spring cage terminals on the XTMCXF block, and does it matter?
Both are offered on the 4-pole 4NO block: XTMCXFA40 is screw terminal, XTMCXFC22 is spring cage. Screw is the familiar choice for field service and matches most existing panels wired with screw terminations; spring cage is faster to wire in volume and holds under vibration without retorquing, which is why OEM machine builders usually specify it. Keep one type across a panel so techs are not carrying two sets of habits.
7) How much current can these Eaton auxiliary contacts carry?
Conventional thermal current is 10A. That is enough for control-circuit duty: pilot lights, PLC inputs, relay coils, solenoid valves, interlock strings. It is not a power pole, so do not run a motor load through it.
8) What is the equivalent auxiliary contact if my panel uses ABB contactors instead of Eaton?
The XTMCXF block only suits Eaton XTRM relays. On an ABB-based panel, the comparable accessory is the ABB CR305X Series auxiliary contact for contactors and relays. For fuse-holder and disconnect signalling, the Bussmann BAC Series auxiliary contact covers a 1A to 12A range.
9) Will adding this block cost me rail space in a tight enclosure?
No added rail width. The XTMCXF mounts to the front face of the relay rather than to the side, so it grows the assembly forward into the door clearance instead of consuming DIN rail. Check your depth to the enclosure door, not your rail length.
10) My panel drawing calls out IEC 60947 for the auxiliary contact. Does the Eaton XTMCXF meet that, and do the alternatives?
The Eaton XTMCXF auxiliary contact is built to comply with IEC 60947 and is CE Marked, so it can be cited directly against an IEC 60947 callout. Among the comparable blocks, the ABB CR305X series and the Bussmann BAC series are auxiliary contacts for their own respective device families, and you would confirm the standards line on whichever manufacturer's device the block is mounting to. If the drawing also fixes the relay brand as Eaton XTRM, the XTMCXF is the block that physically matches.
11) Is a Square D Type S isolated alarm contact kit an alternative to the Eaton XTMCXF auxiliary contact?
They serve different circuits. The Square D 9999SO4 is a Type S isolated alarm contact kit, an accessory that provides an isolated alarm contact on Square D Type S starters and overload relays. The Eaton XTMCXF is a front-mounted auxiliary contact block for Eaton XTRM miniature control relays, offered in 2-pole and 4-pole NO/NC arrangements at 10A conventional thermal current for general interlocking and signaling. Use the Square D kit for alarm indication on a Square D starter, and the Eaton block when you need extra poles on an Eaton relay.
12) For fuse or disconnect blown-fuse signaling, is the Bussmann BAC a better fit than the Eaton XTMCXF?
Yes, for that job. The Bussmann BAC series auxiliary contact covers a 1A to 12A amp range and is a Bussmann accessory intended for use with its fuse and disconnect hardware. The Eaton XTMCXF auxiliary contact is purpose-built as a front-mounted add-on for Eaton XTRM miniature control relays and carries a 10A conventional thermal current rating. Choose by what the contact has to attach to: Bussmann's for the fuse gear, Eaton's for the XTRM relay.
13) How many auxiliary blocks come in a pack?
The XTMCXF auxiliary contact is supplied in quantities of 5, which suits stocking a service van or building a run of identical panels rather than buying one-off.
