- Overview:
- Din rail adjustable over under voltage protector device protective relay Digital current voltage protector.
- Digital display self-compound over-under-voltage and over-current auto-reclosing protector is a comprehensive intelligent protector integrating over-voltage protection, under-voltage protection, over-current protection and over-current protection. When there is over-voltage fault, under-voltage fault and over-current fault in the circuit, this product can cut off the power supply instantly and protect the electrical equipment from being burnt out.When the line returns to normal, the protector can automatically restore power.
- The overvoltage value, undervoltage value, overcurrent value and delay value of this product can be set by itself, and the corresponding parameters can be adjusted according to the actual situation of users.
