Product Description
Schneider Electric LC1D25 TeSys Deca Contactor — 25A, 3-Pole
The Schneider Electric LC1D25 is a 25A, 3-pole IEC contactor from the TeSys Deca series (formerly known as TeSys D). Rated 25A AC-3 and 40A AC-1 in a compact 45mm frame, it is designed for motor control and power switching in pumps, compressors, conveyors, HVAC equipment, and industrial control panels. The LC1D25 includes built-in 1 N.O. and 1 N.C. auxiliary contacts as standard, and it can be configured with additional auxiliary contact blocks and compatible overload relays to suit the application.
This page is presented as a configurable LC1D25 product. The final catalog number depends on the selected coil voltage, and the optional auxiliary contact and overload relay selections above determine the final configured assembly for ordering.

Product Features
- Built-In 1 N.O. + 1 N.C. Auxiliary Contacts: Standard on the LC1D25 for signalling and interlocking. Additional auxiliary contact blocks can be added where more control contacts are needed.
- Compact 45mm Frame: Shares the same compact frame width used across the TeSys Deca D09–D38 range, making it well suited to high-density panel layouts.
- Multi-Standard Screw Terminals: Screw terminal connections accept flat, Phillips, and Pozidriv screwdrivers for easier installation and servicing.
- Direct-Mount Overload Relay Options: For motor starting use, the LC1D25 can be paired with compatible TeSys thermal overload relays such as LRD32, or with electronic overload relays such as LR9D32, depending on the motor full-load current.
- Suitable for Motor and Power Switching Duties: Commonly used in pumps, compressors, conveyors, machinery, and OEM control panels where a 25A IEC contactor is required.
- TeSys Deca Platform: The current TeSys Deca branding replaces the earlier TeSys D commercial name while retaining the established LC1D25 platform and part-number structure.
Frequently Asked Questions
What does LC1D25 mean?
The part number follows Schneider Electric’s TeSys Deca naming convention: LC1 identifies the IEC contactor family, D designates the TeSys D / TeSys Deca frame series, and 25 identifies the 25A AC-3 current rating. The suffix identifies the coil voltage — for example, LC1D25G7 is the 120V AC version and LC1D25BL is the 24V DC version.
Does the LC1D25 include auxiliary contacts?
Yes. The LC1D25 includes 1 N.O. + 1 N.C. auxiliary contacts as standard, so the base contactor already provides one normally open and one normally closed control contact for signalling and interlocking. If your application needs more control contacts, compatible front-mount and side-mount auxiliary contact accessories can be added without changing the base LC1D25 platform.
What overload relay pairs with the LC1D25?
For direct mounting beneath the LC1D25, Schneider lists compatible TeSys Deca thermal overload relays for the D25–D38 frame, including ranges such as LRD22 (16–24A) and LRD32 (23–32A), depending on the motor nameplate full-load current. For electronic overload protection, LR9D32 (6.4–32A) is the matching electronic relay for D09–D38 frames.
How do I choose the right coil voltage?
Choose the coil voltage that matches your control circuit voltage, not the motor line voltage. For example, if the control circuit is 120V AC, the correct LC1D25 suffix is typically G7; if the control circuit is 24V DC, the matching version is typically BL. If you need help matching the suffix to your control power, see Schneider coil voltages and the difference between coil control voltage and line voltage.
Can the LC1D25 be used for hermetic refrigeration compressor duty?
Yes — AC coil versions only. The LC1D25 carries a definite purpose rating for hermetic refrigeration compressor applications of 25 FLA, with locked-rotor ampere ratings of 150A at 240V, 125A at 480V, and 100A at 600V.
What is the difference between AC-1 and AC-3 ratings?
AC-1 and AC-3 are different IEC utilization categories. AC-1 applies to resistive or only slightly inductive loads, so it is the broader non-motor switching rating, while AC-3 applies to starting and switching squirrel-cage motors, where the contactor must handle higher inrush and motor-duty switching conditions. On the LC1D25, that is why the AC-1 rating is 40A while the motor-duty AC-3 rating is 25A. For more background, see AC1 versus AC3 electrical amp ratings.
