Schneider Electric LC1D12 Contactor

Schneider Electric LC1D12 Contactor – TeSys Deca Series

Overview

The Schneider Electric LC1D12 is a rugged, high-performance 3-pole contactor from the TeSys Deca Series(formerly TeSys D). Rated for 12 Amps AC-3, it provides dependable motor control for three-phase power systems, pumps, HVAC units, and industrial automation.

Fully compliant with IEC 60947, UL 60947, and CSA C22.2, the LC1D12 offers the same compact DIN-rail designand modular flexibility as the smaller LC1D09, but with a higher current rating for motors up to 5.5 kW (7.5 HP).

🔑 Key Features

• Rated Current (AC-3): 12 A

• Power Rating: Up to 5.5 kW / 7.5 HP at 400 V (3-phase)

• Operating Coil Voltage Options: 24 V, 48 V, 110 V, 230 V (AC & DC voltage versions)

• Operating Voltage (Nominal): 220 V AC

• Coil Type: Low-inrush electromagnetic power relay coil for quiet, efficient operation

• Contact Type: 3 main poles + 1 auxiliary (NO or NC)

• Mounting: Quick DIN-rail or screw mount

• Terminals: Heavy-duty screw terminals

• Compliance: UL 60947, IEC 60947, CSA C22.2

• UNSPSC: 39121529

⚡ Applications

The LC1D12 is ideal for:

• Electric motors up to 5.5 kW (7.5 HP)

• Reversing contactors and star-delta starters

• Control panels and power distribution systems

• Water treatment plants, HVAC equipment, and industrial automation racks

Its robust AC-3 rating and superior coil voltage stability make it perfect for continuous-duty service in demanding environments.

🧱 Construction & Design

Like all TeSys Deca Series devices, the LC1D12 features a compact DIN-rail design that accepts the same accessories as the LC1D09 and LC1D18.
The relay coil minimizes inrush consumption, extending both electrical life (>1 million operations) and mechanical life (>10 million cycles).
