Product details

It's rated AC-3 at 12 A up to 440 V, which means it's sized for switching three-phase motor loads in that current range: conveyors, pumps, small crusher feeders. The coil pulls in on 12 V DC, so it's a straight fit for a 12 VDC control supply — common in mobile equipment or PLC-driven panels where you're running a 24 VDC bus with a step-down. AC-1 and AC-4 utilisation categories are also listed, so it covers resistive loads and plugging/inching duty as well.

Built to take the punishment of a mineral processing line

This contactor shrugs off the vibration you get on a crusher floor or a mill motor starter. It's rated for 4 Gn vibration closed and 2 Gn open over 5–300 Hz, and shock-tested to 15 Gn closed on the Z axis — all per IEC 60068-2-6 and IEC 60068-2-27. That means it stays closed under the hammering of a conveyor start or a nearby breaker trip. The IP20 finger-safe housing (per VDE 0106) keeps dust and tools out of the live terminals, but it's meant for a panel — not open washdown. Flame retardance is V1 per UL 94, so it meets the self-extinguishing requirement for enclosed industrial control gear. Operating altitude is 2000 m without derating, which covers most mine sites and high-country installations.

Frequently asked questions

What are the key ratings of LP5K12105JW3?

It is a three-pole reversing contactor rated AC-3 at 12 A up to 440 V, with a 12 V DC coil. It also covers AC-1 and AC-4 utilisation categories. The housing is IP20, and it withstands vibration up to 4 Gn closed and shock up to 15 Gn on the Z axis.

What compliance documentation is available for this part?

The contactor carries a V1 flame-retardance rating per UL 94, and the IP20 protection is per VDE 0106. It also meets NF F 16-101 and NF F 16-102 for flame retardance. Standard Schneider Electric compliance documentation (RoHS, REACH, UL, IEC) is available from the manufacturer.
