Finding the Correct Cross Reference for Telemecanique LC1D Contactors

To cross a Telemecanique LC1D contactor to a BRAH Electric replacement, put a B in front of the full Telemecanique number: LC1D0910-G7 becomes BLC1D0910-G7. The rule holds for every LC1D09 through LC1D95 listing in the BRAH catalogue. On the large frames, LC1D115 through LC1D620, the BRAH number also takes a dash before the coil letters, so LC1D115B6 becomes BLC1D115-B6.

LC1D is the type code for TeSys D contactors with an AC coil. The rest of this guide shows how to read the number, gives one row for each LC1D size with its catalogue ratings, and lists the coil voltage behind each suffix so you can confirm the match before ordering.

LC1D cross-reference at a glance

• The catalogue holds 222 BRAH replacements for LC1D contactors across 19 sizes. All are 3-pole and rated 600V.
• Cross by the complete number from the nameplate, including the digits after the size and the letters after the dash.
• The suffix sets the coil voltage. -G7 is listed as 110/120VAC, -U7 as 240VAC and -T6 as 480VAC. The full list is in the suffix table.
• Do not read an amperage out of the number. The catalogue rating of the LC1D09 replacement is 25A, not 9A.
• For a number that is not in the tables, use the search box on the contactors listing or call (855) 355-2724 with the part number.

How to read an LC1D part number

Take LC1D5011-T6 as the example. It splits into four parts:

• LC1D is the type. In the catalogue, LC1D is a contactor with an AC coil, LC2D is the reversing version and LP1D is the version with a DC coil.
• 50 is the size. It is a size code, not a current rating.
• 11 is the built-in auxiliary contact. The catalogue lists 10 as one normally open contact, 11 as one normally open and one normally closed, and 01 as one normally closed.
• -T6 is the coil. The catalogue lists -T6 as 480VAC.

So LC1D5011-T6 crosses to the BLC1D5011-T6: size 50, 1 NO / 1 NC, 480VAC coil. In the catalogue the 10 arrangement appears on sizes 09 through 32 and the 11 arrangement on sizes 40 through 95. A number with the size alone, such as LC1D25, is listed with the standard contact for that size and a 110/120VAC coil.

BRAH replacements for each LC1D size

Each row is one size. The linked part is the base listing for that size, and the last column counts every listing of that size, including the coil-voltage variants.

The amperage column needs care. For these Telemecanique contactors the catalogue figure is higher than the size code suggests (25A against LC1D09, 60A against LC1D40), which reads as a general current rating and not a motor rating. Do not select by that column. Select by the number on the nameplate of the contactor you are replacing, and check the motor nameplate horsepower and voltage against the horsepower column.

Coil suffixes and the voltage listed for each

This table covers the LC1D09 through LC1D95 listings. Each suffix maps to one coil voltage across all of them. The example part is one listing with that suffix.

The -P7 and -Q7 listings are on sizes 25 through 95. On the large frames, LC1D115 through LC1D620, the coil voltages listed are 24VAC, 110/120VAC, 120VAC, 220VAC, 240VAC, 480VAC, and the coil letters follow the size directly in the Telemecanique number (LC1D150T6). Whatever the suffix, confirm the coil voltage shown on the product page against the marking on the installed coil. Some suffix pairs, such as -G6 and -G7, share a voltage. In the BRAH coil listings for these contactors, a final 6 goes with a 60Hz coil and a final 7 with a 50/60Hz coil.

LC1D, LC2D and LP1D: make sure you have the right type

Three type codes look alike on a worn nameplate. They are different products, and each has its own BRAH replacements.

If only the coil has failed, the contactor may not need replacing. BRAH lists replacement magnetic coils for TeSys D contactors, along with LR2D overload relays and LA1D and LA8D auxiliary contact blocks. The guide to choosing an LC1D0910 replacement works through one size in detail.

Step by step: crossing a number

• Write down the full number from the contactor nameplate, not from the panel drawing. Parts get changed over the years and the drawing may be out of date.
• Split it into type, size, auxiliary digits and coil suffix as shown above.
• Add the B. For LC1D115 and larger, add a dash before the coil letters as well.
• Open the product page and compare coil voltage, auxiliary contact and horsepower with the installed contactor and the motor nameplate.
• If the page and the nameplate disagree on anything, stop and call before ordering.

Before you order: what to match

• Coil voltage and frequency, read from the coil itself and from the control circuit.
• AC or DC coil. An LC1D number has an AC coil and an LP1D number a DC coil.
• Built-in auxiliary contact: 1 NO, 1 NC or 1 NO / 1 NC, plus any add-on block fitted to the old contactor.
• Motor horsepower and supply voltage against the catalogue horsepower.
• The overload relay. If it stays, check that it suits the replacement. If it is being changed, pick its range by the motor full-load current.
• Mounting and terminal positions, compared with the photos and drawings on the product page.

The catalogue marks the original Telemecanique numbers as obsolete. BRAH Electric designs its replacements in-house and tests them at its Carlsbad, California facility. BRAH is an aftermarket manufacturer, not an authorized distributor of the OEM brand. Replacement contactors carry a 2-year warranty from the date of invoice, and help with a cross-reference is available on (855) 355-2724, Monday to Friday, 6AM to 5PM Pacific.

Safety note

Cross-referencing is desk work, but reading a nameplate inside a live panel is not. Have a qualified person open the enclosure, and if the contactor has to be handled or removed to read it, de-energize the circuit, apply lockout/tagout and verify the absence of voltage first.

LC1D cross-reference FAQs

What does LC1D mean on a Telemecanique contactor?

It is the type code. In the BRAH catalogue, type LC1D covers TeSys D contactors supplied with an AC control coil. The digits after it give the size and the built-in auxiliary contact.

Does LC1D09 mean the contactor is rated 9A?

Do not rely on that. The digits are a size code. The catalogue rating of the BRAH replacement for the LC1D09 is 25A and 5HP. Take ratings from the nameplate and the product page.

Can I replace an LC1D contactor with an aftermarket part?

Yes, when the replacement is listed as a direct substitute for your exact number and the coil voltage and auxiliary contact match. The BRAH parts in this guide are described in the catalogue as direct substitutes for the Telemecanique numbers shown.

How do I know what coil voltage I need?

Read the marking on the installed coil and check the control circuit drawing. Then confirm that the suffix on your part number maps to that voltage in the suffix table.

My number has no dash and no letters. What coil does it have?

In the catalogue, LC1D numbers with no coil suffix are listed with a 110/120VAC coil, shown as 120VAC on some of the large frames. Check the coil on your contactor before relying on that.

Does BRAH Electric help with cross-references?

Yes. Call (855) 355-2724 or use the contact page and give the full number from the nameplate.
