5 FAQs of Current Transformer AC Low Voltage Transformer LMZJ1 400/5 500/5 600/5 0.2S

What is the LMZJ1 Current Transformer?
It measures high alternating current (AC). It steps down the current to a safe, low level. This level is easy for meters and protective relays to handle. Models include 400/5, 500/5, and 600/5. This means 400A, 500A, or 600A primary current becomes 5A secondary current.

Where is the LMZJ1 typically used?
It is installed inside low-voltage switchgear. This includes panels and cabinets. Its job is accurate measurement and system protection. You find it in power distribution networks and industrial settings. It connects to meters, relays, and control devices.

What are the key features?
Its core design uses laminated silicon steel. This ensures good performance. It has a window-type (through-hole) construction. This makes installation over busbars simple. It meets the 0.2S accuracy class. This means very precise measurements, especially at low currents. It’s built for reliability in demanding environments.

What does the 0.2S accuracy class mean?
0.2S is a high accuracy rating. The transformer can measure current with a maximum error of 0.2%. This error applies under specific conditions. The “S” part is important. It means the transformer stays accurate even when the current is very low. This is down to just 1% of its rated current. This precision is crucial for energy metering.

How is it installed?
The primary conductor passes through its center window. This conductor is the circuit’s main busbar or cable. The secondary terminals connect to the measurement device. Use the correct wires.
