Schneider Electric LC1D40A | TeSys D 40A 3P Contactor Base Model
Base model Schneider Electric LC1D40A TeSys D contactor. 3-pole, 40A AC-3 rating, 18.5kW motor control. Requires coil voltage suffix (e.g., AB7, F7) for full specification.
Product Overview
The Schneider Electric LC1D40A is the base reference for a 40 A frame size 3-pole contactor in the TeSys D series (also known as TeSys Deca). This model number denotes the core 40A power component without a predefined coil voltage; it must be ordered with a suffix (e.g., LC1D40AB7 for 24V AC, LC1D40AF7 for 110V AC) to specify the control circuit. It is designed for switching 3-phase motors up to 18.5 kW (400V) and features a modular design that accepts add-on auxiliary contact blocks.

Key Features
-
Modular Design: The base unit (LC1D40A) is a "naked" contactor; auxiliary contacts (NO/NC) and timers must be added as separate blocks.
-
High Compatibility: Designed to pair with TeSys D overload relays (e.g., LRD21, LRD35) for complete motor starter assemblies.
-
Flexible Control: Coil voltage is not fixed, allowing selection of 24V, 48V, 110V, 220V AC/DC variants based on the application's control circuit.
-
High Breaking Capacity: Rated for 690V AC systems and motor inrush currents (AC-3 duty).
Applications
-
Motor starter combinations for 15–20 kW pumps and fans
-
Industrial control panels and MCC (Motor Control Center) buckets
-
HVAC and compressor control circuits
