Hong Hock Technology has completed development of a full range of CNC adapter solutions for upgrading Masterpact M and Masterpact NW air circuit breakers to the Schneider Electric MTZ platform.
What We Offer
Our adapters are mechanically developed and site-proven from 800A up to 3200A, covering the most common frame sizes used in Singapore’s industrial and commercial switchboards.
- Masterpact M → MTZ retrofit adapter
- Masterpact NW → MTZ retrofit adapter
- NS800 → NW / MTZ transition solutions
All adapters are designed for direct drop-in replacement — existing panel cradles, busbars, and secondary wiring remain unchanged.
Why Retrofit Instead of Replace?
Replacing an ACB in an existing switchboard typically requires panel modification, extended downtime, and significant cost. Our CNC adapter approach eliminates these barriers:
- No panel modification required
- Minimal downtime — typically completed in a single shift
- Full compliance with Schneider Electric MTZ specifications
- Suitable for oil & gas, marine, and industrial applications
