Schneider Electric TeSys D contactor 3P 18A AC3 24V DC 1NO+1NC LC1D18ABL

The Schneider Electric LC1D18ABL is a high-performance contactor from the TeSys D series, designed for reliable switching of motors and other inductive loads. With 3 poles, a rated operational current of 18 A in AC-3 category (up to 440 V), and a 24 V DC control circuit, this contactor is ideal for industrial automation and control applications. It features one normally open (NO) and one normally closed (NC) auxiliary contact, screw clamp terminals, and can be mounted on rail or plate. The contactor complies with IEC 60947-4-1, UL 508, and CSA C22.2 No 14 standards, ensuring global acceptance.

Advantages

Compact design saves panel space; high electrical and mechanical durability (2 million cycles AC-3, 15 million cycles mechanical) ensures long service life; integrated auxiliary contacts reduce need for additional components; wide operating temperature range (-5 to 60 °C) suits demanding environments; IP20 protection on front face for safety.
