The automatic machine of protection of a network of three-phase alternating current AZ3K-5 is intended for protection of a power network from dangerous on value and time of current overloads.
Automatic machines are dustproof also vlagoustoychiva.
Automatic machines of protection of a network with an index "K" are installed in cabins with red lighting and differ in the extended handle and absence on it the shining peephole.
- the AZ3 and AZ3K (8Yu0.361.030TU) type on currents from 2 to 50 And
- AZ3K (8Yu0.619.253TU) 75 A type
- AZZ and AZ3K (8Yu0.619.253TU) 100 type A
Structure of a symbol:
- AZ3 - type designation: automatic machine of protection of a network of three-phase
- To - a setting point:
- without index K - in cabins with normal lighting;
- with an index K - in cabins with red lighting;
- X - rated current, And.
