CNC Adapter Retrofits: Masterpact M / NW to MTZ — 800A to 3200A
We've fully developed CNC adapter solutions for replacing ageing Masterpact M and NW breakers with the latest MTZ platform — no panel modification required from 800A to 3200A.
Specialist electrical contractor in Singapore — VSD replacement, ACB retrofitting, PLC systems, switchboard modification, and protection relay migration. Not general maintenance. The jobs others turn away.
The jobs general contractors turn away — the VSD nobody can diagnose, the PLC migration with no documentation, the ACB without a drop-in replacement. That's where we start.
We replace VSDs across all major brands for cranes, hoists, cryogenic pumps, and industrial fans. When standard panel enclosures don't exist, we fabricate custom VSD panels to spec — including offshore-rated builds deployed internationally.
Custom PLC solutions built without dependency on SCADA systems. We handle full machine migrations from obsolete controllers, trace starter and control circuit faults from first principles, and deliver working systems with proper documentation.
Our fully developed CNC adapter series covers Masterpact M → NW → MTZ retrofits from 800A to 3200A, plus C801 to NS800 transition solutions. Cradle and wiring replacement is still required — but the CNC-machined adapter eliminates the need to modify existing busbars, significantly reducing panel downtime and rework.
Most contractors replace the entire ATS controller on failure. We diagnose at the component and circuit level, which means faster resolution and lower cost when the fault is traceable. We only recommend full replacement when repair genuinely isn't viable.
Custom switchboard extensions and busbar modifications, sized and modelled in full 3D CAD before a single piece is cut. This eliminates fit-up surprises during installation and gives clients a visual sign-off before fabrication begins.
For clients planning a capacity increase or simply unsure what they're consuming — we hook up metering on-site, monitor usage patterns over the study period, analyse max demand, and deliver a formal energy demand study report. The essential step before any tariff upgrade or load expansion.
We handle the full migration from Areva Micom and Schneider Micom relays to Schneider Electric Easergy P Series, and from Schneider Sepam to Easergy. This covers relay configuration, protection setting transfer, wiring adaptation, and commissioning — ensuring protection philosophy is preserved through the transition to modern platform.
In-house 3D CAD and 3D printing capability for custom industrial parts — adapter brackets, bespoke enclosures, replacement components, and prototyping. Where standard parts are unavailable or lead times are unacceptable, we design to spec and produce in-house.
VSD servicing and preventive maintenance across all major brands, including capacitor reforming for drives that have been out of service. High-power component replacement — IGBTs, capacitors, resistors, and other power-stage parts in VSDs, UPS systems, and industrial drives. UPS battery replacement and system health checks. General electrical installation, fault-finding, and repair for industrial and commercial facilities.
Alongside specialist work — not the headline, but part of every engagement.
