Selection of 3-pole Class 20 Bimetallic and Class 10 Solid-state Overload Relays

Differential (Single Phase Sensitive) Thermal Overload Relays

Compensated relays with manual or automatic reset, with relay trip indicator, for ac or dc

LR2-D1508 to 2553: independent mounting either by ordering a terminal block LA7D1064 or LA7D2064, or by ordering the relay pre-assembled; in this

case, add the suffix LA7 to the reference.

Example: LR2D1508 becomes LR2D1508LA7.

Other Versions

Power terminals can be protected against direct finger contact by the addition of shrouds and/or insulated terminal blocks, to be ordered separately

(see page 113).

For use with D25-D38 contactors, order spacer clip (part number W816366180111). See page 137.

These overloads are available without single phase sensitivity. To order, change the LRD prefix to LR3D and add A1 to the end of the number.

Example: LRD1508 becomes LR3D1508A1
