ALP series intelligent low-voltage line protectors are suitable for low-voltage systems with rated voltages up to AC 400V, rated currents up to AC 6300A, and rated frequencies of 50/60Hz. The product integrates protection, measurement, control, and bus communication. It also provides functions such as remote automatic control, on-site direct control, panel instructions, signal alarms, operation records, trip alarm records, and switch value records.
As a new intelligent integrated device for the protection, monitoring, and control of low-voltage feeder terminals, the product is suitable for coal mines, petrochemicals, smelting, electric power, ships, and civil buildings.
