Schneider LC1D40 Magnetic Contactor 40A 220V

The Schneider LC1D40 magnetic contactor is a three-pole contactor designed for motor control and suitable industrial electrical applications. The LC1D40M7 version uses a 220V AC 50/60Hz coil and has a 40A AC-3 rated operational current. It belongs to Schneider Electric’s TeSys D contactor range.

The Schneider LC1D40 is designed for switching three-phase electrical loads where the contactor’s current, voltage and utilization-category ratings match the application. Its 3-pole, 3-NO configuration allows the three main phases to be switched through the contactor. The device also includes auxiliary contacts for control and signalling functions.

One important point when selecting this contactor is the difference between its AC-3 operational rating and thermal current rating. The LC1D40 is commonly described as a 40A contactor, while the thermal current can be 60A under the specified conditions. For motor-control applications, the 40A AC-3 rating is the more relevant figure and should not be replaced with the 60A thermal rating when selecting the contactor.

The LC1D40M7 version has a 220V AC control coil operating at 50/60Hz. Customers should verify the complete model number before ordering because Schneider manufactures LC1D contactors with different coil voltages. Matching the coil voltage with the control circuit is essential for correct operation.

This Schneider LC1D40 contactor can be used in suitable motor starters, industrial control panels, pumps, compressors, HVAC systems, machinery and other electrical control applications. The exact motor power and application suitability should always be checked against the motor nameplate, operating voltage, current and applicable utilization category.

If you are searching for a Schneider LC1D40 contactor in Pakistan, checking the complete model number is particularly important. LC1D40M7 identifies the 220V AC coil version, while the newer LC1D40AM7 is listed by Schneider as a replacement for LC1D40M7.

HN Electric supplies electrical and industrial products for customers in Lahore and across Pakistan. Before installation, verify the contactor’s AC-3 rating, operating voltage, coil voltage and motor requirements against the manufacturer’s specifications.

FAQs

Q1. What is the current rating of Schneider LC1D40?
The LC1D40 has a 40A AC-3 operational rating. Its thermal current is higher under specified conditions, so 60A should not be treated as its AC-3 motor rating.

Q2. What is the coil voltage of LC1D40M7?
The LC1D40M7 version uses a 220V AC 50/60Hz coil.

Q3. How many poles does LC1D40M7 have?
It is a 3-pole, 3-NO contactor.

Q4. Is LC1D40 suitable for motor control?
Yes. Schneider specifies the TeSys D LC1D40 for motor-control applications, provided the load and electrical conditions are within the applicable ratings.
