Use
DL - 30 series of current relays for motor, transformer and transmission line overload and short-circuit protection circuit, as the starting element.
Main technical data
| Error of motion: | The error of each setting is not greater than 6%; |
| Return coefficient: | Not less than 0.8; |
| Action time: | When the action value of 1.1 times, the action time is no more than 0.12s; |
| Contact capacity: | When the voltage is not greater than 250V and current less than 2a, contacts disconnect power, this 50W 5 + 0.75ms time constant inductance load DC circuit with, in AC circuit for 250VA. |
| Power consumption: | The minimum setting value, the relay coil power consumption does not exceed 20VA. |
