SCHNEIDER ELECTRIC LC1D12

Schneider Electric TeSys D 3-Pole Contactor

Description

This is a Schneider Electric LC1D12 contactor from the renowned TeSys D series. It is engineered for high performance in motor control and resistive load applications. With a robust design, it offers a long mechanical and electrical life. This 3-pole contactor is rated for 5.5 kW motor loads at 400V (AC-3 category) and has a conventional thermal current of 25A. It comes equipped with one built-in normally open (NO) and one normally closed (NC) auxiliary contact. Note: The coil voltage for this specific unit is not marked and should be verified prior to installation.

FAQ

Question?
What is the coil voltage for this specific LC1D12 contactor?

The coil voltage is not specified on the exterior markings of this unit. The full part number (e.g., LC1D12M7 for 230V AC) typically denotes the voltage. It is crucial to identify the coil voltage before applying control power to terminals A1 and A2.

Question?
What is the difference between the AC-3 rating (12A) and the Ith rating (25A)?

The AC-3 rating of 12A is the maximum operational current for switching a squirrel-cage motor. The Ith (conventional free air thermal current) of 25A is the maximum current the contactor can carry continuously in open air without exceeding temperature limits, typically used for resistive loads (AC-1 category).

Question?
Can I add more auxiliary contacts to this contactor?

Yes, the TeSys D series is modular. You can add front-mount or side-mount auxiliary contact blocks (e.g., LADN series) to increase the number of available NO or NC contacts.
