LRD 01...35
3-pole Thermal Overload Relays
Use in Explosive Atmospheres
e 0080
II (2) GD - Zones 1 - 2, 21 - 22
EC type examination certificate:
INERIS 06ATEX0036X
Description
LRD 21pp
LRD01 to LRD35 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.
1 Adjustment dial Ir.
2 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. Relays LRD 01 to 35 are supplied with the
selector in the manual position, protected by a cover. Deliberate action is required
to move it to the automatic position.
