Description

LC1D25E7

The Schneider Electric LC1D25E7 is a compact and reliable TeSys D series contactor designed for motor control and electrical switching in industrial and commercial panels. It features three main poles (3 NO) with a 25 A AC-3 rating suitable for motors up to around 11 kW at 400 V, and includes a 48 V AC coil for safe control circuits. Built-in auxiliary contacts (1 NO + 1 NC) enhance flexibility for control logic. It supports DIN-rail or panel mounting and meets multiple international standards (IEC, UL, CSA, CCC, EAC), offering durable performance in demanding environments.

The LC1D25E7 is a TeSys D series industrial contactor designed to switch and control electrical power circuits using a 48 V AC control coil and three main power poles (3NO). It’s rated for up to 25 A switching current and suitable for loads up to about 11 kW at 400 V AC in typical motor applications.

Main Uses

1. Motor Switching & Control

The most common use of this contactor is to start and stop 3-phase AC motors — for example:

• Pumps

• Fans

• Compressors

• Conveyor belts
  It’s designed for AC-3 duty, meaning it can handle the high inrush currents seen when a motor starts.

2. Industrial Motor Starters

It’s often used as the main contactor in motor starter circuits, paired with:

• Overload relays

• Circuit breakers
  This combination protects and controls motors in industrial machinery.

3. Control Panels

LC1D25E7 is widely used inside electrical control panels for:

• Power distribution switching

• Logic control circuits

• Remote or automated on/off control
  The built-in auxiliary contacts (1 NO + 1 NC) help interfaces with PLCs or safety systems.

4. Resistive Load Switching

Although mainly for motors, it can also switch resistive loads (heating elements, lighting circuits, etc.) under the right conditions (AC-1 duty).

5. Automation Systems

Useful in automated systems where a control signal (e.g., from a PLC or control relay) needs to:

• Turn equipment on/off

• Sequence operations

• Provide feedback via auxiliary contacts
  This makes it suitable in factory automation or building management systems.

6. General Power Switching

It works wherever reliable switching of medium-power AC circuits is needed — such as:

• HVAC systems

• Pumps in water treatment systems

• Conveyors in packaging machines

• Industrial ovens
  Thanks to its compact size and DIN-rail or panel mounting

Key Features That Support These Uses

• 48 V AC coil for standard low-voltage control.

• 3 main power contacts (3NO) for three-phase load control.

• Auxiliary contacts (1NO + 1NC) for control logic and feedback.

• Compact size & DIN-rail mountable for control panels.

• Rated for AC-3 duty (motor loads) and AC-1 (resistive loads).
