Product Name:
Schneider LC1D40008M7 – TeSys D Contactor
1. Overview:
The LC1D40008M7 is a 4-pole contactor from Schneider Electric’s TeSys D series. It is designed for switching general-purpose electrical loads (AC-1 duty) such as resistive loads, heating elements, and lighting circuits.
This model supports up to 60A at 440V, and uses a 220V AC coil (50/60 Hz) for control operation. It has a 2 NO + 2 NC contact configuration.
2. Key Specifications:
Feature | Description |
---|---|
Contactor Type | Electromechanical, 4 poles (2 NO + 2 NC) |
Rated Current (AC-1) | 60A – for non-inductive or slightly inductive loads |
Main Circuit Voltage | Up to 440V AC |
Control Coil Voltage | 220V AC, 50/60 Hz |
Contact Arrangement | 2 Normally Open (NO) + 2 Normally Closed (NC) |
Series | TeSys D – modular, compact, and durable |
3. Functionality:
-
AC-1 Duty Application:
Designed for non-motor loads such as:-
Heating circuits
-
Lighting loads
-
Capacitor banks
-
Distribution systems
-
-
4-Pole Switching:
Allows switching of three phases plus neutral or use in two separate circuits. -
Versatile Contact Setup (2NO + 2NC):
-
NO (Normally Open): Closes when coil is energized – powers the load.
-
NC (Normally Closed): Opens when coil is energized – often used for interlocking or control logic.
-
4. Coil and Operation:
-
220V AC Coil:
Accepts standard mains voltage (single-phase), commonly used in control panels. -
Silent and Efficient:
The TeSys D series is known for low coil power consumption and mechanical durability.
5. Applications:
-
Resistive Load Control (heaters, ovens)
-
Lighting Systems
-
Power Distribution Switching
-
Controlling Neutral + 3 Phase lines
-
Automation Panels
-
Control Logic Circuits (using NO/NC contacts)
6. Installation & Integration:
-
Mounting:
Compatible with DIN rail or screw mounting. -
Expandable:
Can be equipped with auxiliary contacts, timers, or mechanical interlocks. -
Compatible with TeSys Accessories:
Such as overload relays and interface modules.
7. Summary:
The Schneider LC1D40008M7 is a 60A, 4-pole contactor designed for AC-1 applications (non-inductive loads), with a 220V AC control coil. It features 2 NO + 2 NC contacts for flexible wiring in heating, lighting, or distribution systems. Reliable, durable, and part of the modular TeSys D series, it is widely used in industrial and commercial installations.
