Compatibility and replacement
For separate mounting on a rail or plate Schneider offers a terminal block adapter (LAD7B106 for LRD01-35). If the motor current is near the top of the range, use the next range up so the setting sits mid-scale.
Frequently asked questions
What does class 10A mean?
It is the trip class per IEC 60947-4-1: at 7.2 times the setting current the relay trips within 2 to 10 seconds, which suits standard motors with normal starting times.
What current range does it cover?
23 … 32 A, set on the front dial.
Does it detect phase loss?
Yes. Schneider gives the phase failure sensitivity as: Tripping current 130 % of Ir on two phase, the last one at 0.
Can it be mounted separately from the contactor?
Yes, with the Schneider terminal block adapter for independent mounting on a rail or plate.
