Product details

Part at a glance

The LP4K09008SW3 is a 4-pole TeSys contactor from Schneider Electric, switching resistive loads up to 20 A AC-1 at 690 V. It operates on a 72 V DC control voltage with integral surge suppression. Rated 20 A in AC-1 utilisation category – sized for resistive or slightly inductive loads like heaters or lighting. The 4-pole arrangement gives 2 NO + 2 NC power contacts. Coil hold-in power is 1.8 W, and the control circuit accepts a wide DC range from 0.7 to 1.3 Uc. Mechanical durability is rated at 30 million cycles; electrical endurance at 0.16 million cycles at 20 A AC-1.

Integration notes

Mounts on rail or plate. Screw clamp terminals accept 1.5 to 4 mm² solid or 0.75 to 4 mm² flexible wire; tightening torque 0.8 to 1.3 Nm. IP2X finger protection. Overall dimensions: height 58 mm, width 45 mm, depth 57 mm. Standards include IEC 60947-4-1, UL 60947-4-1, and CSA C22.2 No 60947-4-1 – covering European and North American panel approvals. Flame retardance is V1 per UL 94.
