TELEMECANIQUE LC1-D633 LX1D6M7

Telemecanique LC1-D633 3-Pole Contactor

Description

The Telemecanique LC1-D633 is a high-performance 3-pole contactor designed for motor control and other demanding switching applications. As a predecessor to the modern Schneider Electric TeSys D range, this contactor is known for its durability and reliability in industrial settings. It is rated for 63A in AC-3 applications and 80A in AC-1 applications, with a maximum operational voltage of 660V.

FAQ

What is the difference between the AC-1 and AC-3 rating on this LC1-D633 contactor?

AC-1 rating (80A) is for non-inductive or slightly inductive loads, like resistance heaters. The AC-3 rating (63A) is specifically for squirrel-cage motors and applies to starting and switching off motors during running, which is a more demanding application.

Can I replace the 220V AC coil (LX1D6M7) with a different voltage coil?

Yes, the coils in the Telemecanique D-series contactors are generally interchangeable. You can replace the existing LX1D6M7 coil with another LX1D6 series coil of the correct voltage (e.g., 24V DC or 110V AC) to match your control circuit.

Is this Telemecanique LC1-D633 directly compatible with modern TeSys D accessories?

While the core design is similar, there may be slight mechanical differences. Many TeSys D accessories, like front-mounted auxiliary contacts (LADN series) and overload relays (LRD series), are often compatible. However, it is always best to verify compatibility for specific accessory models before purchasing.
