N-pole protection, current unbalance protection, MCR making capacity protection
■ Maintenance function: With fault record (8 times), historical current peak record, contact wear
equivalent, query of operation times, clock function, self-diagnostic function, test function and fault
display function
■ With a remote reset device, realize remote recovery (optional accessories) after fault tripping of the
controller
1.5.4 Integrated communication network
The NWK22/NWK32 type controller can realize remote sensing, remote control, remote regulating and
remote communication - "four remotes" data transmission function through the communication interface (to be
used with the communication adapter and signal unit).
With the communication adapter, realize the conversion of DeviceNet and Profibus-DP protocols for data
transmission.
1.5.5 AC 1140V circuit breaker
The HU (AC1140V) type circuit breaker and XU (AC1140/1380/1500V) type circuit breaker are selected,
which can be used in the power distribution system in special fields such as metallurgy, rail transportation, pipe
gallery, energy saving and environmental protection.
1.5.6 Three-proofing circuit breaker
The TH (thermal-humidity) type circuit breaker can meet the three-proofing requirements of moisture-
proofing, mould-proofing and salt spray-proofing, and complies with JB/T834 Technical Requirements of
Tropical Type Low-voltage Apparatus while having passed the following standard related tests:
