Product Description

Masterpact MT adopts new technology to enhance product performance and safety. It is a new-age product with easy installation, user-friendly interface, convenient operation and easy design.

Supply Advantage & Procurement Notes

The Masterpact MT air circuit breaker serves as a cost-effective alternative to the Schneider NW series, offering lower pricing and shorter lead times.

Because domestic and international models differ, selection requires precise parameter matching and accessory configuration—capabilities many suppliers are unable to support reliably.

Standard Features

Masterpact MT series circuit breakers have drawer type/fixed type, 3/4 pole switch Provide load switch, 1000V, and DC products, divided into seven breaking types:

  • N1: Current level 630A to 1600A, breaking capacity 50KA, standard type, suitable for breaking low-level short-circuit current
  • N2: Current level 800A to 2500A, breaking capacity 50KA, suitable for general applications
  • H1: Current level 800A to 6300A, breaking capacity 65KA, suitable for breaking high-level short-circuit current in industrial environments or electrical systems with two transformers running in parallel
  • H1b: Current level 800A to 4000A, breaking capacity 85kA, suitable for industrial industries with large short-circuit currents
  • H2: Current level 800A to 6300A, breaking capacity 100KA, high-performance type, suitable for heavy industrial fields that may generate very high short-circuit currents
  • H3: Current level 800A to 4000A, breaking capacity 150KA, suitable for occasions that require both high-performance breaking capacity and high-level coordination
  • L1: Current level 800A to 2000A, breaking capacity 150KA, with high current limiting capability to protect the feeder unit or improve the performance level of the switchgear when the rated power of the transformer is increased
