Tesys D line Overload Relays
The normally closed overload contact are terminals 95 & 96; and the normally open overload contact are terminals 97 & 98.
T1 T2 and T3 are the load terminals.
The normally closed control circuit contact will open when there is a fault, this contact is typically used in series with the control circuit.
The normally open trip signal contact closes when a fault occurs which is typically used to control a pilot light, or alarm.
The correct code is LRD332.
You can use the Everlink range which is LRD313 - LRD365
17-25 Amps = LRD325
23-32 Amps =LRD332
Following are the differences between the LC1D50U7 and the LC1D50AU7:
LC1D50AU7 has everlink terminals.
LC1D50AU7....is slightly larger case and accommodate LRD3XX overloads
LC1D50U7 contactors accommodate LRD33XX overloads.
The setting range is 37 - 50A
Part code for the overload LRD3365
