The Schneider Electric TeSys LP1K12004FD is a 4-pole contactor with a 110 V DC coil, rated for 20 A in AC-1 utilisation category (resistive loads) up to 690 V. The 4 NO power poles give you four independent switching paths, so it handles single-phase or three-phase resistive loads with a spare pole for a neutral or auxiliary circuit.
At 45 mm wide, 58 mm tall, and 57 mm deep, it takes up a standard 4-module footprint on the rail — that's another SKU that fits the same slot as the rest of the TeSys LP1K family. Screw-clamp terminals accept 1.5 to 4 mm² solid or stranded, with a tightening torque of 0.8 to 1.3 N·m. IP2X means finger-safe but not washdown-rated; keep it inside the enclosure.
What the approvals tell you
Certified to EN/IEC 60947-4-1 and -5-1, plus UL 60947-4-1 and -5-1, and CSA C22.2 No 60947-4-1 and -5-1. That covers both power switching and control-circuit duty across IEC and North American jurisdictions. Also carries GB/T 14048.4 for the Chinese market. Flame retardance is V-0 per UL 94.
