Masterpact:presentation

Masterpact circuit breakers are used to protect and control low-voltage distribution systems. They may be installed in main LV switchboards (incoming units, main and secondary outgoers). Masterpact is a complete range offering a large selection of performance levels: c ratings from 800 to 6300 A AC, from 1000 to 8000 A DC; c breaking capacity from 40 to 150 kA rms; c operational voltages690 V AC, 1000 V DC.

Many versions c 3 or 4 poles; c fixed or drawout versions; c current-limiting version up to 2500 A; c wide range of control units offering multiple functions. Circuit breakers designed for all applications c 1000 V AC version; c DC version; c anti-corrosion version; c source-changeover version; c merchant-marine and military versions. Masterpact circuit breakers comply withall major international standards and meet T2 tropicalisation criteria.
