Contactor Schneider TeSys LC1-D 4P (2F+2O) 25A AC-1 440V - Ref. LC1D128P7



The Schneider Electric TeSys LC1-D128P7 contactor is a professional modular device designed to control and protect resistive loads up to 25 A AC-1. With its 4-pole configuration (2 NO main contacts + 2 NC main contacts) and its 230V AC 50/60Hz coil, this contactor fits perfectly into residential and tertiary electrical panels for remote control of power circuits.





Typical applications

  • Residential electric heating: radiators, convectors, underfloor heating (purely resistive loads)
  • Pumps and circulators: swimming pool pumps, water circulation systems, booster pumps
  • Power lighting: floodlights, halogen lamps, outdoor lighting
  • Light industrial resistive loads: heating resistors, electric ovens, dryers, etc.
  • Centralised control: management of several circuits from one control panel (home automation, BMS)

Why choose the TeSys LC1-D128P7 contactor?

1. Flexible 4-pole configuration (2F+2O)

The contactor has 2 main NO (Normally Open) contacts and 2 main NC (Normally Closed) contacts, offering great flexibility for :

  • Control 2 independent circuits simultaneously (e.g. 2 heating zones)
  • Create alternating control sequences (e.g. switching between two sources)
  • Create mechanical or electrical interlocks to secure installations.



2. Category AC-1: specialist in resistive loads

Optimised for purely resistive loads (power factor ≈ 1), the LC1D128P7 guarantees:

  • Maximum durability: contacts rated for 600,000 AC-1 operations.
  • No significant arcing: minimal contact wear
  • Proven reliability: TeSys technology proven for decades



3. 230V AC 50/60Hz coil: easy integration

The 230V AC 50/60Hz coil allows direct control from :

  • Programmable time switches
  • Electronic thermostats
  • Control contactors
  • PLCs and home automation systems (via intermediate relay)



4. DIN rail mounting: quick installation

The contactor mounts on a standard 35mm DIN rail, making it easy to :

  • Integration into modular enclosures
  • Replacement of existing equipment
  • Preventive and corrective maintenance





🔧 Installation and use



Connection diagram (typical)

  • Main contacts: connection of power circuits (phase(s) + neutral)
  • Coil A1/A2: 230V AC power supply from control circuit
  • Auxiliary contacts (optional): status signalling or interlocking



⚠️ Warning: The contactor has no overload protection. It must be used in conjunction with :

  • A thermal-magnetic circuit breaker suitable for the load current (e.g. 25A curve C)
  • Or a thermal motor protection relay (if used for specific applications).



Installation advice

  • Ventilation: allow 10-15mm clearance above/below for heat dissipation
  • Wiring: use rigid or flexible conductors with ferrules (cross-section 0.75 to 4 mm²)
  • Tightening torque: 1.7 Nm (power and control terminals)
  • Checking: test the control without load before commissioning under load





Integration in photovoltaic and energy installations

The TeSys LC1-D128P7 contactor can also be used in solar and energy storage systems:



  • Electric heating control: controlling heating resistors using photovoltaic surpluses (smart grid)
  • Hot water tank management: automatic activation during hours of solar production
  • Source switching: switch between mains/generator in emergency systems (with interlock)
  • Pump control: control of circulators for solar thermal systems or swimming pools
