TeSys D power contactor AC3 12A 3P 1NO 1NC 48VDC coil LC1D12ED

Power contactor – reliable motor control

This three-pole TeSys D power contactor, with a rated current of 12A, is designed to control three-phase motors and various types of industrial loads. Its compact design and high reliability make it an ideal solution for both installers and end-users.

This contactor finds application in HVAC systems, refrigeration equipment, pumps, as well as in general industrial applications.

Design and functionality

The LC1D12ED contactor has screw connection of the main contacts, which facilitates assembly and connection of wires. A 48V DC powered coil provides reliable control. Built-in auxiliary contacts – 1NO (normally open) and 1NC (normally closed) – increase the functionality of the device and allow for the implementation of more complex control circuits. The contactor design allows for mounting on a DIN rail or direct screw mounting, providing installation flexibility.

Applications and benefits

• Versatility: Suitable for controlling motors up to 5.5 kW at 400V AC-3 and 3.7 kW at 400V AC-4.
• High durability: Designed for operation at a frequency of up to 3600 cycles per hour, guaranteeing long-lasting and reliable operation in demanding industrial conditions.
• Safety: Compliance with many standards (IEC, UL, CSA, CCC, EAC, Marine) ensures safe use and meets stringent industry requirements.
• Easy integration: The ability to directly mount LRD overload relays on the contactor simplifies the motor protection circuit configuration. Additional auxiliary contacts LADN are easy to install and provide additional control functions.
• Sustainable development: Green Premium product meets environmental protection requirements (RoHS/REACh), confirming the manufacturer's commitment to sustainable development.
• Compact dimensions: A width of only 45 mm allows for efficient use of space in control cabinets.
• Adapted to harsh conditions: Operation at temperatures up to 60°C guarantees reliability even in demanding industrial environments.
