Power connection
LRD 01 to LRD 35
LRD 01 to 35 relays are designed for connection by screw clamp terminals.
They can be supplied for connection by spring terminals or by lugs (1).
LRD 313 to LRD 365
LRD 313 to 365 relays are for connection by BTR screw connectors (hexagon socket
head).
The screws are tightened by means of a size 4, insulated Allen key.
This type of connection uses the EverLink® system with creep compensation (2)
(Schneider Electric patent).
This technique makes it possible to achieve accurate and durable tightening torque.
These relays are also available for connection by lugs (1).

Description
TeSys D 3-pole thermal overload relays are designed to protect a.c. circuits and
motors against overloads, phase failure, long starting times and prolonged stalling
of the motor.
Adjustment dial Ir.
Test button.
Operation of the Test button allows:
- checking of control circuit wiring,
- simulation of relay tripping (actuates both the N/O and N/C contacts).
3 Stop button. Actuates the N/C contact; does not affect the N/O contact.
4 Reset button.
5 Trip indicator.
6 Setting locked by sealing the cover.
7 Selector for manual or automatic reset.
LRD 01 to 35 and LRD 313 to LRD 365 relays are supplied with the selector in theand LRD 313 to LRD 365 relays are supplied with the selector in therelays are supplied with the selector in the
manual position, protected by a cover. Deliberate action is required to move it to the
automatic position.

(1) Connection by lugs meets the requirements of certain Asian markets and is suitable forConnection by lugs meets the requirements of certain Asian markets and is suitable for
applications subject to strong vibration, such as railway transport.
(2) Creep: normal crushing phenomenon of copper conductors, that is accentuated over time.
