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. 526212 LRD 21pp DB110937 Environment Conforming to standards Product certifications Degree of protection Protective treatment Ambient air temperature around the device IEC 60947-1, IEC 60947-4-1, NF C 63-650 VDE 0660, BS 4941 CSA, UL, Sichere Trennung, ATEX except LAD 4: UL, CSA.
