APC TeSys D LC1D32B7 3-Pole Contactor 24 V DC 32 A 1 NO + 1 NC Auxiliary

The APC LC1D32B7 is a high-performance 3-pole contactor from the TeSys D series, designed for reliable motor control and switching applications. With a rated operational current of 32 A in AC-3 category and a control circuit voltage of 24 V DC, this contactor is ideal for industrial automation, HVAC systems, and machinery control panels. It features screw clamp terminals, DIN rail or plate mounting, and complies with international standards IEC 60947, UL 508, and CSA C22.2 No 14.

Advantages

Robust construction ensures long electrical and mechanical durability (1.6 million cycles electrical, 30 million cycles mechanical). Compact design saves panel space. Integrated 1 NO + 1 NC auxiliary contacts provide flexibility for control logic. IP20 protection on front face safeguards against accidental contact.
