TeSys D power contactor AC3 18A 3P 1NO 1NC coil 380VAC LC1D18Q7

TeSys D Power Contactor – Reliable Motor Control

This 3-pole TeSys D power contactor with a rated current of 18A is a robust solution for controlling motors in demanding industrial and construction applications. It is ideal for heating, ventilation and air conditioning (HVAC) systems, pumps, conveyors and other equipment requiring frequent switching. The contactor's design is engineered for long-term reliability and ease of installation.

Construction and Application

The LC1D18Q7 contactor has screw connections, making installation and wiring easier. It is equipped with a 380V AC coil, compatible with 50/60Hz power supplies. Built-in auxiliary contacts (1NO + 1NC) provide additional functionality, such as contactor status signaling or control of auxiliary circuits. The contactor is designed to operate in harsh conditions, withstanding up to 3600 operating cycles per hour at an ambient temperature of up to 60°C. This makes it a reliable component in even demanding industrial environments.

Key Advantages and Features
