Product details

The LRD3361A66 is a differential thermal overload relay from the Schneider TeSys LRD family, rated for motor protection with a thermal protection adjustment range of 55-70 A and a Class 10A trip curve per IEC 60947-4-1.

The relay carries approvals under EN/IEC 60947-4-1, UL 60947-4-1, and CSA C22.2 No 60947-4-1, so it's accepted in panels destined for North American and European installations. The IP20 finger-safe enclosure and V1 flame-retardance rating (UL 94) are standard for control-panel use — no special handling for washdown or outdoor exposure.

Frequently asked questions

What is the adjustment range of this relay?

The thermal protection adjustment range is 55-70 A, set via an integral dial. The trip threshold is factory-calibrated to 1.14 ± 0.06 times the set current per IEC 60947-4-1.

What standards does LRD3361A66 comply with?

It meets EN/IEC 60947-4-1, EN/IEC 60947-5-1, UL 60947-4-1, UL 60947-5-1, CSA C22.2 No 60947-4-1, CSA C22.2 No 60947-5-1, GB/T 14048.4, and GB/T 14048.5. Insulation voltage is rated 1000 V per IEC and 600 V per UL/CSA.
