General-purpose time relay
General-purpose time relay GPTR is designed for integration into mine set electrical equipment (compact stations and control stations) and start-protection apparatus with voltage up to 1140 V of alternate current and frequency 50 Hz, which functions as a device to set time delay in mining machines and mechanisms control circuits.
The relay can be designed in the following versions:
- GPTR-01 — for integration into mine set electrical equipment;
- GPTR-02 — for integration into mine start-protection apparatus.
Electrical equipment and apparatus with the integrated relay are to have minimum ingress protection rating lP54. The relay is intended for operation in cold-temperature climatic regions and is produced in the version MCC (moderately cold climate) category 5 according to State Standard 15150-69.
Depending on the operational mode the relay provides on/off switching delay of actuating contacts for the selected time within the range limit (range I — 0-10 seconds; range II — 0-10 minutes) and causes short-term (maximum 1 s) supply voltage rise up to 150% from the rated voltage.
