General Specification — Schneider TeSys D 3P (3NO) Contactors

• Brand / Series: Schneider Electric TeSys D (LC1D) contactor.

• Poles: 3P — 3 main power poles with three normally-open (3NO) contacts. 

• Utilisation Category: Rated for AC-1, AC-3, AC-4 operations (motor and general loads).

• Rated Operational Voltage (Power Circuit): Up to 690 V AC (three-phase mains). 

• Rated Operational Current (Ie): Depends on model — e.g., 9 A, 25 A–32 A, 40 A, 65 A, 80 A at AC-3 duty. 

• Control Coil Voltage: Available with AC or DC coil options (e.g., 24 V DC, 110 V AC, 220–240 V AC, etc.). 

• Auxiliary Contacts: Usually includes 1 NO + 1 NC auxiliary contact for control logic feedback. 

• Rated Impulse Withstand Voltage: 6–8 kV conforming to IEC standards.

• Control Types: AC or DC coil versions available depending on model needs.

• Mounting: DIN-rail or panel mount (compact modular design).

• Applications: Remote switching of three-phase motors, pumps, compressors, HVAC loads, automation panels.

What “3P (3NO)” Means

• 3P: The contactor has three power poles — one for each phase in a three-phase system.

• 3NO: It has three normally-open power contacts; these close when the coil is energized, allowing current to flow through all three phases.

Example Performance (General)

• A 32 A TeSys Deca contactor with 3NO can switch up to 15 kW at 400 V AC in AC-3 motor duty. 

• Rated currents and utilisations vary by model — always match the contactor rating to your load’s full operating current.
