Schneider Electric LC1D32M7C TeSys D IEC Contactor

Important Notes

• The LC1D32M7C is part of the TeSys D series with an AC coil; DC coil variants exist with different voltage ratings

• The contactor includes a protective cover for IP20 front-face safety

• For overload protection, pair this contactor with a TeSys LRD thermal overload relay (e.g., LRD32, range 23-32A) to complete a motor starter assembly

• When used in safety circuits, the NC mirror contact (built-in) provides feedback that meets ISO 13849-1 requirements

• This model is available as both imported and locally produced versions depending on region

FAQ

Q1: What is the difference between LC1D32M7 and LC1D32M7C?

A: The "C" suffix typically designates a specific regional variant or packaging type. Technically, both share the same core specifications: 32A (AC-3), 3 poles, 220V AC 50/60Hz coil, and 1NO+1NC auxiliary contacts. Always verify with your local datasheet for exact regional differences.

Q2: What is the maximum motor power the LC1D32M7C can control?

A: At 400V AC in AC-3 utilization category, it can control motors up to 15 kW. Power ratings vary by voltage: 7.5 kW at 230V, 15 kW at 400-440V, and 18.5 kW at 500-690V.

Q3: What coil voltage does the LC1D32M7C require?

A: The contactor operates on a 220 V AC 50/60 Hz control circuit. The "M7" in the part number indicates the coil voltage code (M = 220V AC).

Q4: Does the LC1D32M7C have built-in auxiliary contacts?

A: Yes, it comes with 1 NO + 1 NC built-in auxiliary contacts. The NC contact is a mirror contact certified for safety feedback applications.

Q5: What is the electrical endurance of this contactor?

A: The electrical durability is 1.65 million cycles at 32A AC-3 operation (≤440V) and 1.4 million cycles at 50A AC-1 operation (≤440V).

Q6: Can the LC1D32M7C be used with a thermal overload relay?

A: Yes, it is designed to be paired with TeSys LRD series thermal overload relays (e.g., LRD32, range 23-32A) for complete motor starter protection.

Q7: Is the LC1D32M7C suitable for DC applications?

A: The power circuit has a rated operational voltage up to 300 V DC, making it suitable for certain DC load switching applications, though its primary design is for AC motor control.

Q8: What certifications does this product hold?

A: It holds CCC, CE, UKCA, CSA, UL, EAC, and Marine certifications, ensuring compliance with international standards.

Q9: What are the physical dimensions of the LC1D32M7C?

A: Approximate dimensions: 45 mm width × 85 mm height × 92 mm depth. It weighs approximately 0.375 kg.

Q10: What is the difference between utilization categories AC-3 and AC-1?

A: AC-1 is for resistive loads (e.g., heating) with a rated current of 50A. AC-3 is for motor starting and switching (squirrel cage motors) with a rated current of 32A. AC-3 involves higher inrush currents during starting, hence the lower continuous current rating.
