Product details

It is rated for AC-3 utilisation category at 115 A, meaning it is sized for motor switching duty — the current it can make and break under load. The coil is 24 V AC. The unit has 3 x 3P (3 NO) power poles, so nine normally-open main contacts across three contactors.

Pollution degree 3 means it tolerates conductive pollution in industrial atmospheres. Storage range is -60 to 80 °C. It is rated for operation up to 3000 m altitude without derating.

Construction and environmental ratings

The housing is rated V1 flame retardance per UL 94 and withstands 850 °C glow-wire per IEC 60695-2-1. Protective treatment TH per IEC 60068-2-30 covers tropical humid conditions. Mechanical robustness: 2 Gn vibration (5-300 Hz) with contactor open, 4 Gn when closed; shock resistance 6 Gn open, 15 Gn closed for 11 ms.

Frequently asked questions

What is the LC3D115B7's range and product name?

It belongs to the TeSys range and the product name is TeSys D.

What compliance documentation is available for the LC3D115B7?

The part carries UL 94 V1 flame retardance, IEC 60695-2-1 850 °C fire resistance, and IEC 60068-2-30 TH protective treatment. The manufacturer's standard declarations (RoHS, REACH) would apply to the TeSys D series, but specific certificates for this obsolete code should be requested with the RFQ.

How do I source the LC3D115B7?

Since it is obsolete, it is sourced through surplus and broker channels. Submit an RFQ for a quote and availability — the supply posture is quoted to order, not off-the-shelf.
